PART I 

ITEM 1.    BUSINESS.
 
Overview
 
We are one ofSummit’s vision is to be the fastest growingmost socially responsible, integrated construction materials companies in the United States,solution provider, collaborating with a 55% increase in revenue between the year ended January 2, 2016 (the year ofstakeholders to deliver differentiated innovations and solve our initial public offering) and the year ended December 28, 2019.customers’ challenges. Within our markets, we offerstrive to be a market leader by offering customers a single‑sourcesingle-source provider for construction materials and related vertically integrated downstream products through our vertical integration.products. 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‑mixready-mix concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our vertical integrationvertically integrated business model 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 believe we have becomeare a major participant in the U.S. construction materials industry. We believe that, by volume, we are aindustry as our sales volumes of aggregates put us in the top 10 of aggregates supplier,suppliers, a top 15 cement producer and a major producer of ready‑mix concrete and asphalt paving mix. Our proven and probable aggregates reserves and resources were 3.95.7 billion tons as of December 28, 2019.31, 2022. In the year ended December 28, 201931, 2022 we sold 54.059.5 million tons of aggregates, 2.42.5 million tons of cement, 5.55.0 million cubic yards of ready-mix concrete and 5.63.7 million tons of asphalt paving mix across our more thannearly 400 sites and plants.
 
The rapid growth we have achieved overIn the last 10 years has been due in large part to our acquisitions, which we funded through equity issuances, debt financings and cash from operations. Overdecade following the past decade,great financial crisis, 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. TheMore recently, the U.S. private construction market has grown in recent years both nationally and in our markets.markets while public infrastructure spending has been a steady contributor to overall construction market growth. We believe we are well positioned to capitalize on this growth to continue to expand our business.business by capitalizing on growth in the construction market, but any near-term economic slowdown or recession would challenge our industry growth and, as a result, our growth plans.

Our revenue in 20192022 was $2.2$2.4 billion with net income attributable to Summit Inc. of $61.1$272.1 million. As of December 28, 2019,31, 2022, our total indebtedness outstanding was approximately $1.9$1.5 billion.
 
We anticipate continued growth in our primarydemand to vary by 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 7%16% in the U.S. from 20202023 to 2024.2027. By fiscal year 2026, The Infrastructure Investment and Jobs Act (the "IIJA") will provide $52.3 billion in funding to Texas, Utah, Kansas and Missouri, our top four states by revenue in 2022. We believe states will continue to institute state and local level funding initiatives dedicated towards increased infrastructure spending. We believe that growth inHistorically, infrastructure spending will not be consistent across the United States, but willhas varied by geography depending on several factors including underlying economic conditions and fiscal health of individual states. Economic conditions in our markets do vary across different geographies.by state, and public infrastructure funding is expected to differ as a result. The public infrastructure market represented 38%approximately 35% of our revenue in 2019.2022.
 
The private construction market includes residential and nonresidential new construction and the repair and remodelreplace 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 7% from 2020decline as compared to 2024. In addition,historically high levels. Despite this decline, the PCA projects that spending in private nonresidential construction will grow 6% over the same period.7% from 2023 to 2027 and we believe residential activity in our key markets will continue to be a driver for volumes in future periods. 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. The private construction market represented 62%approximately 65% of our revenue in 2019.2022.
 
In addition to anticipated demand growth in our end markets, weWe 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 8%16% in the U.S. from 20202023 to 2024,2027, reflecting rising demand in the major end markets. We believe that the increased demand will drivesupport higher cement pricing as production capacity in the United States tightens.remains tight and the cost of imported cement remains high.

Historically, weWe 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
7

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.businesses and brands.

We also seek greenfield development opportunities, particularly in our current geographies where we have been unable to identify additional acquisition opportunities at reasonable values. While greenfield development opportunities generally take longer to reach positive cash flows, the return on investment can equal or exceed those of business acquisitions.

In March 2021, we launched our Elevate Summit strategy, which included an initiative to divest of 10 to 12 business units which did not meet certain criteria. Since that time, we have divested 11 businesses, including three businesses in 2022 that resulted in net proceeds of $373.1 million, and cumulatively the 11 divested businesses generated $501.4 million in net proceeds. We plan to continue our efforts to optimize our portfolio, which could include future divestitures.

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
8

Federal 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”)Infrastructure Investment and Jobs Act was signed into law on December 4, 2015November 15, 2021. The IIJA legislation provides $1.2 trillion in funding over five years from 2022 through 2026, $347.8 billion for highways, and authorizes $305$91.0 billion of funding from 2016 through 2020. It provides funding for surface transportation infrastructure, including roads, bridges, transit systems, and the rail transportation network.transit.
 

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, we have observed migration trends towards rural and exurban U.S. markets, notably in our Texas and Utah markets. Given the high inflationary pressures, and recent increases in mortgage interest rates, we have begun to see a decrease in residential construction demand has been growing, although the rate of growth has varied across the U.S.activity, which we expect to continue in 2023.
 
Nonresidential Construction.  Nonresidential construction encompasses all privately financed construction other than residential structures. Demand for nonresidential construction is customarily driven primarily by population and economic growth.growth, and activity tends to follow residential activity by 12-24 months. Population growth generally spurs demand for stores, shopping centers and restaurants. Economic growth typically 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 other variables, including interest rates and the availability of credit to finance these projects.
 
Our Competitive Strengths
 
Leading market positions.  We believe each of our operating companies hasseek to obtain a top threetwo market share position in itsour local market area achieved through their respective, extensive operating histories, averaging over 30 years.areas. 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 generally 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 becomeour market leaders.leadership.
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 February 2019 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 and Missouri, three 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%19% 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,the value chain, 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 2322 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 December 28, 2019, we grew our revenue by 55% and brought substantial additional scale and geographic diversity to our operations. In the year ended December 28, 2019, 40%31, 2022, 54% of our operating income increase came from the West segment, 37%19% from East segment and 23%27% from the Cement segment, excluding corporate charges. As of December 28, 2019,31, 2022, we had approximately 3.93.7 billion tons of proven and probable aggregatesmineral reserves serving our aggregates and cement business.1.8 billion tons of measured and indicated mineral resources. We estimate that the useful life of our proven and probable reserves serving our aggregates and cement businesses are approximately 9653 years and 274172 years, respectively, based on the average production rates in 20192022 and 2018.2021.
 
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 2019,2022, we shipped approximately 63%70-80% of cement distributed to our terminals and customers was shippedcement by barge, which is generally more cost-effectivecost‑effective than truck or rail 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

Our Business Strategy
 
Utilize vertically‑We believe our integrated business model creates a distinct competitive advantage to support our growth ambitions. We continue to execute on our Elevate Summit Strategy, which has four key themes:

Market Leadership. We expect to create sustainable advantages in suburban and strategically located operations for growth.exurban communities that enhance total shareholder value. We believe that our vertical integration of construction materials, products and services is a significant competitive advantage that weand being materials focused and improving the quality, and sustainability of our earnings will utilize to growdrive share growth in our existing markets and enterenable entry 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 marginsAsset Light Approach. We seek to maximize aggregates pull through in order to improve capital efficiency, and free cash flow generation throughreduce volatility. Our growth has been a result of the successful execution of our materials-led acquisition strategy and implementation of operational improvements.best practices to drive organic growth. 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. We also believe we can enhance our return on investment by partnering with our customers in asset light partnerships by retaining aggregate supply agreements where possible.

Social Responsibility. We strive to build differentiated, heavy materials solutions to enhance returns and maximize social impact. As our customers focus on their own social responsibility goals, we plan to provide innovative solutions to meet those goals. We view social responsibility, which includes human capital, land use, water and addressing carbon emissions impacts, as a strategic imperative essential to serving the needs of our employees, customers, and communities where we operate. We publish an annual sustainability report aligned with the Sustainability Accounting Standards Board Construction Materials Standard. Our management team includes individualssustainability report describes our safety performance as well as water usage, waste production, and carbon emissions impacts. We seek to proactively address those impacts to align our business activities with decadesthe interests of experience in our industryexternal stakeholders.

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.investment expectations.
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 1.36 million in the United States by 2024. The American Institute of Architects’ Consensus Construction Forecast projects nonresidential construction to grow 2.4% in 2020. We believe that exposure to the public infrastructure, residential and nonresidential end markets across our markets will benefit us as the U.S. economy moves through economic cycles.
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. CompetitionThe industry is constrainedshaped in part by the distance materials can be transported efficiently, resulting in predominantlyprimarily 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
10

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 productsmaterials and materialsproducts 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 primarily 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. FundingThe IIJA passed in November 2021 provides $1.2 trillion in funding over five years from 2022 through 2026, which includes $347.8 billion for the existing federal transportation funding program extends through 2020. 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.$91.0 billion for transit.
 
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 Utah and Missouri, represented approximately 22%24%, 13%17%, 12%10% and 10%, respectively, of our total revenue in 2019.2022.
 
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 branding 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 2322 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 December 28, 2019,31, 2022, approximately 79%82% 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 68%67% of our asphalt paving mix was installed by our paving and related services businesses in the year ended December 28, 2019.31, 2022. 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:
 

sum-20221231_g2.jpg

Aggregates
 
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
11

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 believe we are experiencing an extended economic recovery.
We mine limestone, gravel, and other natural resources from 132125 crushed stone quarries and 104107 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 December 28, 2019,31, 2022, we had approximately 3.95.7 billion tons of provenreserves and probable reservesresources 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 3.95.7 billion tons of proven and probable aggregates reserves 2.3and resources, 2.6 billion, or 60%46%, are located on owned land and 1.63.1 billion are located on leased land.

According to the September 2019 U.S. Geological Survey, approximately 1.5 billion tons of crushed stone with a value of approximately $16.7 billion was produced in the United States in 2018, which was consistent with the 1.5 billion tons produced in 2017. Sand and gravel production was approximately 1.1 billion tons in 2018 and 1.0 billion tons in 2017, valued at approximately $8.6 billion in 2018. 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 2019. In February 2019, the U.S. Geological Survey reported that a total of 1,465 companies operating

3,710 quarries and 176 sales/distribution yards produced or sold crushed stone in 2018 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. Our transportation costs are also increasing, primarily due to driver shortages and elevated fuel costs. 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 and a more restrictive permitting and regulatory landscape have been forcing production sites to move further away from the end‑use locations.
 
Each quarry location is unique with regards to demand for each product, proximity to competition and distribution network. Each of our aggregates operations is responsible for the sale and marketing of its aggregates products. Approximately 79%82% 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.
 
Cement
 
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. Cement is sold either in bulk or as branded products in bags, depending on its final user. 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. The remaining shipments are directed to concrete paving projects or manufacturers of concrete-related products such as block and precast. 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.
  
12

Cement production in the United States is distributed among 91from 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 in the 2019 United States Cement Industry Annual Yearbook, consumption is up from the industry trough of approximately 77.6 million tons in 2010 to approximately 108.8 million tons in 2018 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, China, Greece, and Mexico. The PCA reports that cement imports are above their trough of approximately 7.2 million tons in 2011 versus approximately 16.7 million tons in 2018.
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 distribution 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 91 totalover 90 cement plants in the United States. Competitive factors include price, reliability of deliveries, location, quality of cement and support services. Aligned with our core strategy of sustainability, we converted 100% of our cement production from general use Portland cement to Portland Limestone Cement (PLC) during 2022. Portland Limestone Cement is accepted in all major specifications, approved in all major markets, can be used in all applications in lieu of Portland cement while reducing cement’s embodied CO2 content by up to 10%. 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 2019,we ship approximately 63%70-80% of cement distributed to our terminals and customers was shippedcement by barge, which is significantly more cost‑effective than truck or rail transport.
 
CementThe 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 additional standards including the Hazardous Waste Combustor of the National Emission Standards for Hazardous Air Pollutants– Maximum Achievable Control Technology (“HWC‑NESHAP”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. The cement and water are combined and a chemical reaction process called hydration occurs whereby a paste is produced. This paste or binder represents between 15% to 20% of the volume of the mix that coats each particle of aggregate and serves as the agent that binds the aggregates together, according to the National Ready Mixed Concrete Association (“NRMCA”). The aggregates represent approximately 60% to 75% of the mix by volume, with a small portion of volume (5% to 8%) consisting of entrapped air that is generated by using air entraining admixtures. Once fully hydrated, the workable concrete will then harden and take on the shape of the form in which it was placed.
The quality of a concrete mix is generally determined by the weight ratio of water to cement. Higher quality concrete is produced by lowering the water‑cement ratio as much as possible without sacrificing the workability of the fresh concrete. Specialty admixtures such as high range water reducers can aid in achieving this condition without sacrificing quality. 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.
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. All of these products have cementitious properties that enhance the strength, durability and permeability of the concrete. These materials are available

directly from the producer or via specialist distributors who intermediate between the ready‑mix concrete producers and the users.
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, 358.2 million cubic yards of ready‑mix concrete were produced in 2018, which is a 2% increase from the 350.8 million cubic yards produced in 2017 but a 22% 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, Oklahoma and Colorado markets. Our East segment supplies ready‑mix concrete in the Kansas Missouri, Arkansas, North Carolina, South Carolina, Kentucky and VirginiaMissouri markets and surrounding areas. We operated 69 ready-mix concrete plants and over 700 concrete delivery trucks in the West segment and 5522 ready-mix concrete plants and almost 400over 150 concrete delivery trucks in the East segment as of December 28, 2019.31, 2022. 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. Different types of concrete include lightweight concrete, high performance concrete, self‑compacting/consolidating concrete and architectural concrete and are used in a variety of activities ranging from building construction to highway paving.

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”).
13

 
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.thicknesses.
  
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 82.2 million tons of used asphalt is recycled annually by the industry according to a September 2019 NAPA survey.As of December 28, 2019,31, 2022, we operated 2726 and 235 asphalt paving mix plants in the West and East segments, respectively. Approximately 91%Nearly all 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 68%67% 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 2018 and an estimated 389.3 million tons of asphalt paving mix was produced in 2018 compared to 379.4 million tons produced in 2017. 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. MostMany of our contracts contain adjustment provisions to account for changes in liquid asphalt prices.
 
Customers
 
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 20192022 revenue.
 
Seasonality
 
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, flooding and flooding,drought, can adversely affect our business and operations through a decline in both the use of our products, and demand for our services and our ability to provide our products and 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.
 
Backlog
14

 
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 ana material 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.

EmployeesHuman Capital Resources
    
As of December 28, 2019,31, 2022, we hademployed approximately 6,0004,800 employees, of whomwhich approximately 80%4,500 were employed in the United States with the remainder being employed in Canada. Approximately 79% of our employees are hourly workers, andwith the remainder were salaried employees.being salaried. Approximately 10% 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 within three years. 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.

Approximately 7%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 2022, our recordable incident rate declined 23% compared to fiscal 2021.

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. We achieved gender parity at the Board level with over 50% female Board directors.

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: In addition to competitive 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, and employee assistance programs, among other benefits. 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. During 2021, we implemented an Employee Stock Purchase Plan in which the majority of our employees are union members, with whom we believe we enjoy a satisfactory working relationship.eligible to participate.
 
Legal Proceedings
 
15

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 currently not able to predict the ultimate outcome or cost of the investigation at this time.
Pursuant to an Administrative Order on Consent with the Missouri Department of Natural Resources and later amendment to that Order, Continental Cement paid penalties totaling $100,000 relating to alleged past violations of air pollution control requirements at its Hannibal, Missouri facility.investigation.
 
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.plants, conduct mining activities at our aggregate quarries, operate our ready-mixed concrete plants and lay asphalt. 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 fourthree 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
 
16

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 companyoperations level safety managers. We provide our operating companyoperations 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.

ITEM  1A.    RISK FACTORS

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. FederalThe strength of the construction industry in turn can be substantially affected by macroeconomic and other factors beyond our control, including changes in general economic conditions, political or social trends and unrest, terrorism or war, and natural, climate-related or man-made disasters and extreme weather conditions. In addition, 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.projects, or due to other market factors such as rising interest rates, labor shortages and inflation which have impacted demand more recently and are expected to further impact demand in 2023. In addition, a slow pace of economic activity typically results in delays or cancellations of capital projects.
 
OurWhile our business operations cover a wide geographic area, 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 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 Utah and Missouri, our financial condition, results of operations and liquidity could be materially adversely affected.
 
Our businessindustry is cyclical and requires significant working capital to fund operations.
 
Our businessindustry 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 theThe 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 and our ability to provide our products and 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,have in prior years negatively impacted our operations which affected our financial results. More recently, unusually low water levels on the Mississippi River in late 2022 negatively impacted the shipping of our products as well. Major weather events such as hurricanes, tornadoes, tropical storms, flooding, droughts, wildfires and heavy snows have adversely affected and could adversely affect sales in the near term.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.

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.expensive and can have long lead times to acquire. 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 also 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, higher wages, lower sales volumes and higher costs in some markets, negatively affecting our financial condition, results of operations and liquidity.

We also face competition for some of our products from alternative products, new product technologies, different production and distribution processes and alternative business models. For example, our aggregates, ready mixed concrete, and asphalt and paving businesses may compete with recycled asphalt and concrete products that could be used in certain applications instead of new products and our cement operations may compete with international competitors who are importing products into the United States from jurisdictions with lower production and regulatory costs.
Growth and Portfolio OptimizationRisks
 
The success of our business depends in part on our ability to execute on our acquisition and portfolio optimization strategy.
 
A significant portion of our historical growth has occurred through acquisitions, and we will likely execute acquisition transactions in the future. Acquisitions involve risks that, among other things, the businesses acquired will not perform as expected. 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 timewe have recently disposed of a number of assets and businesses that we did not believe met our long-term investment criteria and through our portfolio optimization program, we are also evaluating additional divestiture opportunities of certain assets and businesses that are not core to timeour business. There can be no assurances that we will be able to recover the current carrying amount of our investments, and in some circumstances, assets or businesses may result in additional impairment expenses or other losses. In addition, we may enter into dispositionsbecome subject to certain contractual indemnity or other transactions involving certain of our assetsobligations or businesses.may fail to successfully deploy sale proceeds. 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 growth hasacquisitions and portfolio optimization efforts have placed, and willmay 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.
19

Table of Contents
 
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.


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.

While we perform significant activities around estimating the quantity and quality of our reserves, if those estimates of reserve quantities and qualities differ significantly from actual results due to unexpected geological conditions, we may exhaust our economically viable aggregates reserves sooner than we expect. If we are unable to acquire replacement aggregate reserves, our financial results may be adversely impacted.
 
Economic Risks
 
Our business could be impacted by rising interest rates.

Our operations are highly dependent upon the interest rate-sensitive construction industry. Therefore, our business may decline as a result of rising interest rates and costs.

20

Table of Contents
Notably, demand in the residential construction market in which we sell our aggregates and ready-mix concrete is affected by interest rates which were recently at historically low levels but have been increasing in recent months. There can be no assurance that interest rates will not continue to increase in the future, affecting our business in an adverse manner. While the residential construction market accounted for 30% of our aggregates business and 60% of our ready-mix concrete business in 2022, we expect volume declines in 2023.

Aside from these inherent risks from within our operations, our earnings are also affected by changes in short-term interest rates. However, rising interest rates are not necessarily predictive of weaker operating results.

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. A government shutdown, and other similar budgetary impasses or reductions, may contribute to uncertainty in regard to government spending and may have adverse effects on the economy. 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 experiencedIf state tax revenues in Texas, Utah, Kansas and Missouri experience state‑level funding pressures caused by lower tax revenues and an inability to finance approved projects.projects, our revenues could be negatively impacted. 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, particularly in the Houston and Salt Lake City geographies, and nonresidential projects stagnate or decline, which in some cases we are already starting to experience, 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.
 
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.
 
21

Table of Contents
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.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, including as a result of inflation, could restrict our ability to operate our business and could have significant impacts on our operating costs.

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.business, and have already in certain cases. 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 coal, diesel fuel, liquid asphalt and other petroleum-based resources, which we consume significant amounts of in our production and distribution processes, couldhave negatively affectaffected the results of our business operations orand may further 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, competition for labor from other industries, changing demographics of the overall work force or otherwise may reduce our operating margin and adversely affect our financial position.

Recent inflation, across several input costs has adversely impacted us. Sustained inflation could result in higher costs for transportation, energy, materials, supplies and labor. Our efforts to recover inflation-based cost increases from our customers may be hampered as a result of the structure of our contracts and the contract bidding process as well as the competitive industries, economic conditions and countries in which we operate. Accordingly, substantial inflation may result in a material adverse impact on our costs, profitability and financial result.

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.business, as well as the ongoing labor and supply shortage.
 
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 coal, diesel, liquid asphalt and cement;

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, including punitive damages, 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.
 
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.occurring. 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 leveragedebt 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 December 28, 2019,31, 2022, our total debt was approximately $1.9$1.5 billion, which includes $1.3$1.0 billion of Senior Notes and $624.3$509.6 million of senior secured indebtedness under our senior secured credit facilities and we had an additional $329.8$325.2 million of unutilized capacity under our senior secured revolving credit facility (after giving effect to approximately $15.2$19.8 million of letters of credit outstanding). In addition, on January 10, 2023, we increased the total aggregate commitments under our senior secured revolving credit facility from $345.0 million to $395.0 million.
 
Our high degree of leverage could havedebt level subjects us to risks with important consequences, including:
 
increasing our vulnerability to general economic and industry conditions;

requiring a substantialsignificant 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;

subjecting 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 arehave less highly leveraged;leverage than we do; 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 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 is the subject of recent national, international and other regulatory guidance and proposals for reform. On July 27, 2017, the United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR by the end of 2021. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2021. The

consequences of these developments cannot be entirely predicted, but could include an increase in the cost of our variable rate indebtedness. 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 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 the greater of (i) $225.0$500.0 million plusand (ii) an additional amount so long as we are in pro forma compliance with a consolidated first lien net leverage ratio. equal to our Consolidated EBITDA for the most recently ended test period.

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
25

Table of Contents
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 cash 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 Chief Executive Officer and other key personnelsenior management team and our ability to retain and attract qualified personnel.
 
Our success depends on the continuing services of key members of our Chief Executive Officer, Tom Hill, and other key personnel led by Mr. Hill.management team. We believe that Mr. Hill in particularour senior management team possesses valuable knowledge and skills that are crucial to our success and would be difficult to replicate or replace. Not all of our senior management team resides near or works at our headquarters. The geographic distance between the members of our senior management team may impede the team’s ability to work together effectively, and we cannot assure they will be able to do so.
 
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 coal, 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. For example, during 2022 the cost of coal, diesel fuel and other petroleum-based resources rose sharply. 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 hasand 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 Canada. Suchthose countries. In addition, in the United States, in part due to the current administration’s focus on climate change as central to U.S. policy, there may be additional legislative and regulatory changes connected to changes in presidential administration. In April 2021, President Biden announced that the United States' Nationally Defined Contribution to the Paris Agreement will be an economy-wide reduction in greenhouse (“GHG”) emissions of 50-52% by 2030, relative to 2005 levels. In addition, in advance of the November 2021 Conference of the Parties 26 meeting in Glasgow, Scotland (“COP26”), the Biden administration released details on its strategy to achieve those targets. The COP26 meeting concluded with international consensus to further reduce GHG emissions, including through the elimination of certain fossil fuel subsidies. In conjunction with COP26, the United States and China also bilaterally agreed to cooperate on GHG emission reductions. Any resulting 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”)GHG emissions from sources considered to be large emitters. The EPA has also promulgated a GHG emissions permitting rule, referred to as the “Tailoring 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. Given the nature of our operations, physical impacts may include disruptions in production and/or regional supply or product distribution networks due to major storm events, shifts in regional rainfall and temperature patterns and intensities, as well as flooding from sea level changes. 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.

Our business is subject to evolving corporate governance and corporate disclosure regulations and expectations, including with respect to environmental, social and governance matters, that could expose us to numerous risks.

We are subject to changing rules and regulations promulgated by a number of governmental and self-regulatory organizations, including the SEC, the New York Stock Exchange (the "NYSE") and the Financial Accounting Standards Board. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by Congress, making compliance more difficult and uncertain. In addition, increasingly regulators, customers, investors and employees and other stakeholders are focusing on environmental, social and governance (“ESG”) matters and related disclosures. These changing rules, regulations and stakeholder expectations have resulted in, and are likely to continue to result in, increased general and administrative expenses and increased management time and attention spent complying or meeting such regulations and expectations. For example, developing and acting on initiatives within the scope of ESG and collecting, measuring, and reporting ESG related information and metrics can be costly, difficult and time consuming and is subject to evolving reporting standards, including the SEC’s recently proposed climate-related reporting requirements,
27

Table of Contents
and similar proposals by other international regulatory bodies. We may also communicate certain initiatives and goals, regarding environmental matters, diversity, responsible sourcing and social investments and other ESG related matters, in our SEC filings or in other public disclosures. These initiatives and goals within the scope of ESG could be difficult and expensive to implement, the technologies needed to implement them may not be cost effective and may not advance at a sufficient pace, and we could be criticized for the accuracy, adequacy or completeness of the disclosure. Further, statements about our ESG-related initiatives and goals, and progress against these goals, may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. In addition, we could be criticized for the scope or nature of such initiatives or goals, or for any revisions to these goals. If our ESG-related data, processes and reporting are incomplete or inaccurate, or if we fail to achieve progress with respect to our goals within the scope of ESG on a timely basis, or at all, our reputation, business, financial performance and growth could be adversely affected.
 
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 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, antitrust, tax, 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.

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, “ransomware” or other malware, denial-of services attacks, hacking, “phishing” attacks, employee or insider error, malfeasance, social engineering, or data leakage of confidential information either internally or at our third‑party providers. In addition, remote work arrangements for our employees could strain our technology resources and introduce operational risks, including heightened cybersecurity risk. Remote working environments may be less secure and more susceptible to hacking attacks. These risks have also impacted, and may in the future impact the third parties on which we rely, and security measures employed by these third parties may also prove to be ineffective at countering threats.

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. OurAny or our vendors’ and third-party service providers’ failure to maintain the security of the data we
28

Table of Contents
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.

Our current information technology platforms and systems require periodic updating and maintenance. Further, we also undertake activities to replace our current systems with technology we believe to be superior to our existing technology. The cost and effort to implement such changes may be significant, and may be more than we initially estimate. These changes may result in our systems being unavailable from time to time, or may not produce the desired results, which may adversely affect our ability to manage and report our results.

Labor disputes, strikes, other forms of work stoppage or slowdown or other union activities could disrupt operations of our businesses.
 
As of December 28, 2019,31, 2022, labor unions represented approximately 7%10% of our total employees, substantially all in our cement division and at our Canadian operations. Our collective bargaining agreements for employees generally expire between 2020 and 2024.within three years. 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.

Outbreaks of contagious disease or similar public health threats could materially and adversely affect our business, financial condition and results of operations.

Outbreaks of contagious disease, including COVID-19, or other adverse public health developments in the U.S. or worldwide could have a material adverse effect on our business, financial condition and results of operations. For example, the emergence and spread of COVID-19 variants could adversely impact our business and results of operations. Outbreaks of contagious disease, including COVID-19, and other adverse public health developments could affect our business in a number of ways, including but not limited to:

disruptions or restrictions on our employees’ ability to work effectively due to illness;
temporary closures or disruptions at our facilities or the facilities of our customers or suppliers could reduce demand for our products or affect our ability to timely meet our customer’s orders and negatively impact our supply chain;
outbreaks of contagious disease could cause delays or disruptions in our supply chain and we could experience a mining or manufacturing slow-down or seek to obtain alternate sources of supply, which may not be available or may be more expensive; and
the failure of third parties on which we rely, including our suppliers, customers, contractors, commercial banks, transportation service providers and external business partners, to meet their respective obligations to us, or significant disruptions in their ability to do so, which may be caused by their own financial or operational difficulties, could have an adverse impact on our business, financial condition or results operations.

The impact of contagious disease or other adverse public health developments could also exacerbate other risks discussed elsewhere in this section of this report, any of which could have a material adverse effect on us.

Tax increases and changes in tax rules may adversely affect our financial results.

As a company conducting business with physical operations throughout the United States and Canada, we are exposed, both directly and indirectly, to the effects of changes in U.S., state and local tax rules. Taxes for financial reporting purposes and cash tax liabilities in the future may be adversely affected by changes in such tax rules. Such changes may put us at a competitive disadvantage compared to some of our major competitors, to the extent we are unable to pass the tax costs through to our customers.

The Biden administration has announced in 2022 and 2021, and in certain cases has enacted, a number of tax proposals to fund new government investments in infrastructure, healthcare, and education, among other things. Certain of these proposals involve an increase in the domestic corporate tax rate, which if implemented could have a material impact on
29

Table of Contents
our future results of operations and cash flows. On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was signed into law, with tax provisions primarily focused on implementing a 15% minimum tax on global adjusted financial statement income and a 1% excise tax on share repurchases. The IRA also creates a number of potentially beneficial tax credits to incentivize investments in certain technologies and industries. Certain provisions of the IRA will become effective beginning in fiscal 2023. While we do not believe the IRA will have a negative impact on our business, the effects of the measures are unknown at this time.
 
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. Deterioration in the financial condition, earnings or cash flow of Summit Holdings and its subsidiaries for any reason, or restrictions on payments by subsidiaries to their parent companies under applicable laws, including laws that require companies to maintain minimum amounts of capital and to make payments to stockholders only from profits, could limit or impair their ability to pay such distributions. Additionally, to the extent that Summit Inc. needs funds, and Summit Holdings is restricted from making such distributions under applicable law or regulation or under the terms of our financing arrangements, or is otherwise unable to provide such funds, it could have a material adverse effect on our financial condition, results of operations and liquidity.
 
Payments of dividends, if any, are at the discretion of our board of directors after taking into account various factors, including our business, operating results and financial condition, current and anticipated cash needs, plans for expansion and any legal or contractual limitations on our ability to pay dividends. Any financing arrangement that we enter into in the future may include restrictive covenants that limit our ability to pay dividends. In addition, Summit Holdings is generally prohibited under Delaware law from making a distribution to a limited partner to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Summit Holdings (with certain exceptions) exceed the fair value of its assets. Subsidiaries of Summit Holdings are generally subject to similar legal limitations on their ability to make distributions to Summit Holdings.
 
Summit Inc. anticipates using certain distributions from Summit Holdings to acquire additional LP Units.
 
The limited partnership agreement of Summit Holdings provides for cash distributions, which we refer to as “tax distributions,” to be made to the holders of the LP Units if it is determined that the income of Summit Inc. will give rise to net taxable income allocable to holders of LP Units. To the extent that future tax distributions Summit Inc. receives exceed the amounts it actually requires to pay taxes and make payments under the TRA, we expect that our board of directors willhas in the past and may in the future cause Summit Inc. to use such excess cash to acquire additional newly-issued LP Units at a per unit price determined by reference to the volume weighted average price per share of the Class A common stock during the five trading days immediately preceding the date of the relevant board action. During the fourth quarter of 2022, Summit Inc. used approximately $59.3 million of such distributions to purchase LP Units. See “Part II, Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities–Dividends.” Although we anticipate that any such decision by our board of directors would be approved by a majority of our independent directors, anyAny cash used by Summit Inc. to acquire additional LP Units would not then be available to fund cash dividends on the Class A common stock.

Summit Inc. is required to pay exchanging holders of LP Units for most of the benefits relating to any additional tax depreciation or amortization deductions that we may claim as a result of the tax basis step-up we receive in connection with sales or exchanges of LP Units and related transactions.
 
Holders of LP Units (other than Summit Inc.) may subject to the vesting and minimum retained ownership requirements and transfer restrictions applicable to such holders as set forth in the limited partnership agreement of Summit Holdings, from and after March 17, 2016 (subject to the terms of the exchange agreement), exchange their LP Units for Class A common stock on a one-for-one basis. The exchanges are expected to result in increases in the tax basis of the tangible and intangible assets of Summit Holdings. These increases in tax basis may increase (for tax purposes) depreciation and amortization deductions and therefore reduce the amount of tax that Summit Inc. would otherwise be required to pay in the

future, although the Internal Revenue Service (the “IRS”) may challenge all or part of the tax basis increase, and a court could sustain such a challenge. future.
 
In connection with the IPO,Summit Inc.'s initial public offering ("IPO"), we entered into a TRA with the holders of LP Units that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result of the increases in tax basis described above and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA. This payment obligation is an obligation of Summit Inc. and not of Summit Holdings. While the actual increase in tax basis and the actual amount and utilization of net operating losses, as well as the amount and timing of any payments under the TRA, will vary depending upon a number of
30

Table of Contents
factors, including the timing of exchanges, the price of shares of our Class A common stock at the time of the exchange, the extent to which such exchanges are taxable and the amount and timing of our income, we expect that as a result of the size of the transfers and increases in the tax basis of the tangible and intangible assets of Summit Holdings and our possible utilization of net operating losses, the payments that Summit Inc. may make under the TRA will be substantial.
 
In certain cases, payments under the TRA may be accelerated or significantly exceed the actual benefits Summit Inc. realizes in respect of the tax attributes subject to the TRA.
 
The TRA provides that upon certain changes of control, or if, at any time, Summit Inc. elects an early termination of the TRA, Summit Inc.’s obligations under the TRA may be accelerated. Summit Inc.’s ability to achieve benefits from any tax basis increase or net operating losses, and the payments to be made under the TRA, will depend upon a number of factors, including the timing and amount of our future income. As a result, even in the absence of a change of control or an election to terminate the TRA, payments under the TRA could be in excess of 85% of Summit Inc.’s actual cash tax savings.
 
The actual cash tax savings realized by Summit Inc. under the TRA may be less than the corresponding TRA payments. Further, payments under the TRA may be made years in advance of when the benefits, if any, are realized on our federal and state income tax returns. Accordingly, there may be a material negative effect on our liquidity if the payments under the TRA exceed the actual cash tax savings that Summit Inc. realizes in respect of the tax attributes subject to the TRA and/or distributions to Summit Inc. by Summit Holdings are not sufficient to permit Summit Inc. to make payments under the TRA. Based upon a $23.84$28.39 share price of our Class A common stock, which was the closing price on December 27, 2019,30, 2022, and a contractually defined discount rate of 3.0%6.48%, we estimate that if Summit Inc. were to exercise its termination right, the aggregate amount of these termination payments would be approximately $289$249 million. The foregoing number is merely an estimate and the actual payments could differ materially. We may need to incur debt to finance payments under the TRA to the extent our cash resources are insufficient to meet our obligations under the TRA as a result of timing discrepancies or otherwise.
 
Ownership of Our Class A Common Stock Risks
 
The market price of shares of our Class A common stock may be volatile,has fluctuated significantly, which could cause the value of your investment to decline.

The market price of our Class A common stock may be highly volatilehas fluctuated significantly in the past and could be subject to wide fluctuations. fluctuations in the future. During the year ended December 31, 2022, the closing price of our Class A common stock on the NYSE has fluctuated from a low of $21.62 per share to a high of $40.77 per share.Securities markets worldwide experience significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could reduce the market price of shares of our Class A common stock regardless of our operating performance. In addition, our operating results could be below the expectations of public market analysts and investors due to a number of potential factors, including variations in our quarterly operating results or dividends, if any, to stockholders, additions or departures of key management personnel, failure to meet analysts’ earnings estimates, publication of research reports about our industry, litigation and government investigations, changes or proposed changes in laws or regulations or differing interpretations or enforcement thereof affecting our business, adverse market reaction to any indebtedness we may incur or securities we may issue in the future, changes in market valuations of similar companies or speculation in the press or investment community, announcements by our competitors of significant contracts, acquisitions, dispositions, strategic partnerships, joint ventures or capital commitments, adverse publicity about the industries we participate in or individual scandals, and in response the market price of shares of our Class A common stock could decrease significantly. You may be unable to resell your shares of Class A common stock for a profit.
 
In recent years, stock markets have experienced extreme price and volume fluctuations. In the past, following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Such litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.
 

Because we have no current plans to pay cash dividends on our Class A common stock, you may not receive any return on investment unless you sell your Class A common stock for a price greater than that which you paid for it.
 
We have no current plans to pay any cash dividends. The declaration, amount and payment of any future dividends on shares of Class A common stock will be at the sole discretion of our board of directors. Our board of directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and
31

Table of Contents
anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us and such other factors as our board of directors may deem relevant. In addition, our ability to pay dividends is limited by our senior secured credit facilities and our Senior Notes and may be limited by covenants of other indebtedness we or our subsidiaries incur in the future. As a result, you may not receive any return on an investment in our Class A common stock unless you sell our Class A common stock for a price greater than that which you paid for it.
 
Future issuance of additional Class A common stock, or securities convertible or exchangeable for Class A common stock, may adversely affect the market price of the shares of our Class A common stock.
 
As of December 28, 2019,31, 2022, we had 113,309,385118,408,655 shares of Class A common stock issued and outstanding, and 886,690,615881,591,345 shares authorized but unissued. The number of unissued shares includes 3,249,6571,312,004 shares available for issuance upon exchange of LP Units held by limited partners of Summit Holdings. Our amended and restated certificate of incorporation authorizes us to issue shares of Class A common stock and options, rights, warrants and appreciation rights relating to Class A common stock for the consideration and on the terms and conditions established by our board of directors in its sole discretion. We may need to raise significant additional equity capital in connection with acquisitions or otherwise. Similarly, the limited partnership agreement of Summit Holdings permits Summit Holdings to issue an unlimited number of additional limited partnership interests of Summit Holdings with designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the LP Units, and which may be exchangeable for shares of our Class A common stock. Sales of substantial amounts of Class A common stock, or securities convertible or exchangeable for Class A common stock, or the perception that such sales could occur may adversely affect the prevailing market price for the shares of our Class A common stock. Thus holders of our Class A common stock will bear the risk of our future issuances reducing the market price of our Class A common stock and diluting the value of their stock holdings in us.
 
AnAs of December 31, 2022, we have reserved an aggregate of 13,500,00017.5 million shares of Class A common stock may be grantedfor issuances under the Amended and Restated Summit Materials, Inc. 2015 Omnibus Incentive Plan (the “Omnibus Incentive Plan”) of which 8,625,745 have been granted, including 7.2 million shares were available for grant as of December 28, 2019.31, 2022. In addition, we also have 5.5 million shares of Class A common stock reserved for issuance under the Summit Materials, Inc. 2021 Employee Stock Purchase Plan (“ESPP”) as of December 28, 201931, 2022. Lastly, as of December 31, 2022, we had outstanding warrants to purchase an aggregate of 100,03731,519 shares of Class A common stock. Any Class A common stock that we issue, including under our Omnibus Incentive Plan, our ESPP or other equity incentive plans that we may adopt in the future, or upon exercise of outstanding options or warrants, or other securities convertible or exchangeable for Class A common stock would dilute the percentage ownership held by the investors of our Class A common stock and may adversely affect the market price of the shares of our Class A common stock.
 
Anti-takeover provisions in our organizational documents and Delaware law might discourage or delay acquisition attempts for us that you might consider favorable.
 
Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make the merger or acquisition of our company more difficult without the approval of our board of directors. Among other things, these provisions:
 
would allow us to authorize the issuance of undesignated preferred stock in connection with a stockholder rights plan or otherwise, the terms of which may be established and the shares of which may be issued without stockholder approval, and which may include super voting, special approval, dividend, or other rights or preferences superior to the rights of the holders of Class A common stock;

prohibit stockholder action by written consent unless such action is recommended by all directors then in office; 

provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws and that our stockholders may only amend our bylaws with the affirmative vote of a majority in voting power of all the then-outstanding shares of stock of the Corporation entitled to vote thereon.

provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws and that our stockholders may only amend our bylaws with the approval of 66 2/3% or more in voting power of all outstanding shares of our capital stock.

establish advance notice requirements for nominations for elections to our board or for proposing matters that can be acted upon by stockholders at stockholder meetings.


Further, as a Delaware corporation, we are also subject to provisions of Delaware law, which may impede or discourage a takeover attempt that our stockholders may find beneficial. These anti-takeover provisions and other provisions under Delaware law could discourage, delay or prevent a transaction involving a change in control of our company, including
32

Table of Contents
actions that our stockholders may deem advantageous, or negatively affect the trading price of our Class A common stock. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions you desire.

AsWe mine a variety of December 28, 2019, we had 3.9 billion tons of provenhard rock materials including limestone, granite, quartzite and probableunconsolidated materials including clay, sand and gravel at our quarry operations. The aggregates produced at our quarries are utilized as general construction aggregates, bituminous asphalt pavement and ready-mix concrete. Our reserves serving our aggregates and cement businesses and operatedresources are across over 400230 sites, and plants, to which we believe we have adequate road, barge and/or railroad access.

A map showing the location of all mining properties is below:

sum-20221231_g3.jpg

We periodically perform sub-surface exploration at most of our sites through drilling methods. At most of our sites, our mining operations are conducted using surface open pit techniques. Mineral resources are defined as having a reasonable prospect of extraction, and is likely to, either in whole or in part, to become economically extractable. Mineral resource estimates were obtained using property boundaries, exploration coverage and regional geologic research. Areas of uneconomically thick overburden or poor aggregate quality rock were defined to the best ability and excluded from reserves or resources areas. Mineral reserves are defined as an estimate of tonnage that can be economically extracted and includes an allowance for losses that may occur when the material is mined or extracted. Mineral reserves estimates were made using similar parameters as for mineral resources. Quantities are counted as reserves based on the nature of the permit, property boundaries, mineral rights and sub-surface exploration. Areas that are not yet permitted or not explored through a drilling campaign are typically excluded from reserves. Due to the nature of our products, we do not perform metallurgical testing, however during exploration, material is tested for construction aggregates and materials or cement suitability.

As of December 31, 2022, we had 3.7 billion tons of proven and probable mineral reserves and 1.8 billion measured and indicated mineral resources. All mineral reserves are reported as saleable tons. All mineral resources are reported as in-situ tons. In total, we owned 46 percent and leased 54 percent of total mineral reserves and resources. We do not consider any of our individual quarrying operations as material for disclosure purposes. We estimate that the useful life of our reserves serving our aggregates and cement businesses are approximately 53 years and 172 years, respectively, based on the average production

Internal Controls Disclosure

The analysis of our reserves and resources has been developed by our personnel in collaboration with Continental Placer Inc. (“CPI”), designated as our qualified person. Our management teams periodically review our reserves by performing sub-surface exploration as part of our mine planning process. Further, we also review and update our mineral resources and reserves as operations progress through our reserves, and as mining permits are submitted for updates and approvals. The modeling and analysis of the Company’s reserves and resources has been developed by Company mine personnel and reviewed by several levels of internal management, including CPI. The development of such reserves and resources estimates, including related assumptions, was a collaborative effort between CPI and Company staff. This section summarizes the internal control considerations for the Company’s development of estimations, including assumptions, used in reserve and resource analysis and modeling.

36

Table of Contents
When determining reserves and resources, as well as the differences between reserves and resources, management developed specific criteria, each of which must be met to qualify as a reserve or resource, respectively. These criteria, such as demonstration of economic viability, legal right to mine, and material quality are specific and attainable. CPI and Company management agree on the reasonableness of the criteria for the purposes of estimating reserves and resources. Calculations using these criteria are either performed or reviewed and validated by CPI.

Estimations and assumptions were developed independently for each geographical operational area. All estimates require a combination of historical data and key assumptions and parameters. When possible, resources and data from generally accepted industry sources, such as governmental resource agencies, were used to develop these estimations.

ITEM  5.     MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES.
 
Market Information
 
Summit Inc.’s Class A common stock began publicly trading on the NYSE under the symbol “SUM” on March 11, 2015. Prior to that time, there was no public market for our Class A common stock. Our Class B common stock is not publicly traded. As of February 3, 2019,13, 2023, there were five holders of record of our Class A common stock and 30 holders of record of our Class B common stock.
 
These stockholder figures do not include a substantially greater number of holders whose shares are held of record by banks, brokers and other financial institutions.
 
All of the outstanding limited liability company interests of Summit LLC are held by Summit Materials Intermediate Holdings, LLC, an indirect subsidiary of Summit Inc. There is no established public trading market for limited liability company interests of Summit LLC.
 
Dividends
  
On December 29, 2022, Summit Inc. paid a stock dividend of 0.017 shares of its Class A common stock for each then outstanding share of Class A common stock as of the record date of December 15, 2022. Summit Holdings makes cash distributions to Summit Holdings’ LP Unit holders to cover tax obligations arising from allocated taxable income. As an LP Unit holder, Summit Inc. received cash distributions from Summit Holdings in excess of the amount required to satisfy Summit Inc.’s tax obligations. In fiscal 2022, Summit Inc. primarily used the excess cash of approximately $59.3 million to acquire newly-issued LP Units from Summit Holdings. The LP Units were purchased at a per unit price of $29.94, which is the volume weighted average price per share of the Class A common stock for the five trading days ended December 2, 2022. Immaterial cash payments were made in lieu of fractional shares.

If Summit Inc. uses future excess tax distributions to purchase additional LP Units, we anticipate that in order to maintain the relationship between the shares of Class A common stock and the LP Units, our board of directors may continue to declare stock dividends on the Class A common stock.
 
Summit Inc. has no current plans to pay cash dividends on its Class A common stock. The declaration, amount and payment of any future dividends on shares of Class A common stock is at the sole discretion of our board of directors and we may reduce or discontinue entirely the payment of any such dividends at any time. Our board of directors may take into account general and economic conditions, our financial condition and operating results, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, and such other factors as our board of directors may deem relevant.

Summit Inc. is a holding company and has no material assets other than its ownership of LP Units. Should we decide to pay a cash dividend on our Class A common stock in the future, we anticipate funding this cash dividend by causing Summit Holdings to make distributions to Summit Inc. in an amount sufficient to cover such dividend, whereupon the other holders of LP Units will also be entitled to receive distributions pro rata in accordance with the percentages of their respective limited partnership interests. Because Summit Inc. must pay taxes and make payments under the TRA, any amounts ultimately distributed as dividends to holders of our Class A common stock are expected to be less on a per share basis than the amounts distributed by Summit Holdings to its partners on a per LP Unit basis.
 
The agreements governing our senior secured credit facilities and the Senior Notes contain a number of covenants that restrict, subject to certain exceptions, Summit LLC’s ability to pay distributions to its parent company and ultimately to Summit Inc. See Note 8, Debt, to our consolidated financial statements.
 
Any financing arrangements that we enter into in the future may include restrictive covenants that limit our ability to pay dividends. In addition, Summit Holdings is generally prohibited under Delaware law from making a distribution to a limited partner to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Summit Holdings (with certain exceptions) exceed the fair value of its assets.

Subsidiaries of Summit Holdings are generally subject to similar legal limitations on their ability to make distributions to Summit Holdings.
 
Issuer Purchases of Equity Securities
 
In March 2022, our Board of Directors authorized a share repurchase program, whereby we can repurchase up to $250.0 million of our Class A common stock. As of December 31, 2022, approximately $149.0 million remained available for share repurchases under the share repurchase program. Under the repurchase program, we are authorized to repurchase shares from time to time in open market transactions, in privately negotiated transactions or otherwise. The repurchase program does not obligate the Company to acquire any specific dollar amount of Class A common stock and may be suspended or discontinued at any time.

During the quarter and year ended December 28, 2019,31, 2022, we did not purchase any of our equity securities that are registered under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Overview
 
We are one ofSummit’s vision is to be the fastest growingmost socially responsible, integrated construction materials companies in the United States,solution provider, collaborating with a 55% increase in revenue between the year ended January 2, 2016 (the year ofstakeholders to deliver differentiated innovations and solve our initial public offering) and the year ended December 28, 2019.customers’ challenges. Within our markets, we offerstrive to be a market leader by offering customers a single-source provider for construction materials and related vertically integrated downstream products through our vertical integration.products. 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 integrationvertically integrated business model 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 completed dozens of acquisitions, whichWe are organized into 1110 operating companies that make up our three distinct operating segments—West, East and Cement. We operate in 2322 U.S. states and in British Columbia, Canada and currently have assets in 2221 U.S. states and British Columbia, Canada. The map below illustrates our geographic footprint:

Business Trends and Conditions
 
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 materials and products and our ability to control operating costs.
 
Our revenue is derived from multiple end-use markets including public infrastructure construction and private residential and nonresidential construction. Public infrastructure includes spending by federal, state, provincial and local governments for roads, highways, bridges, airports and other infrastructure projects. Public infrastructure projects have
historically been a relatively stable portion of state and federal budgets. Residential and nonresidential construction consists of new construction and repair and remodel markets. Any economic stagnation or decline, which could vary by local region and market, could affect our results of operations. Our sales and earnings are sensitive to national, regional and local economic conditions and particularly to cyclical changes in construction spending, especially in the private sector. From a macroeconomic view, we see a positive indicators for the construction sector, including positive trendstrend in highway obligations, but headwinds in housing starts and construction employment.starts.

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. FundingThe Infrastructure Investment and Jobs Act (IIJA) was signed into law on November 15, 2021. The IIJA provides $1.2 trillion in funding over five years from 2022 through 2026, which includes $347.8 billion for the existing federal transportation funding program extends through 2020. 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 the existing infrastructure.$91.0 billion for transit.
 
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 Utah and Missouri, represented approximately 22%24%, 13%17%, 12%10% and 10%, respectively, of our total revenue in 2019.2022. The following is a summary of key funding initiatives in those states:
 
According to theThe Texas Department of Transportation (“TXDOT”), annual funding available Unified Transportation Program is a long-term planning document, released annually, that guides the development of transportation work over ten years. The total ten-year work program for transportation infrastructure, including state and federal funding, is estimated to average $16.2fiscal years 2023-2032 totals $85.1 billion, a 14.3% increase over fiscal years 2022-2031. The first year of the updated plan (fiscal year 2023) calls for $13.6 billion in total forspending, a 58% increase over the first year (fiscal year 2022) of the previous plan.

Total Utah transportation appropriations in fiscal year 2020 (which commenced September 1, 2019) and fiscal year 2021 combined. Further, the 2020 Unified Transportation Program (“UTP”) was approved by the Texas Transportation Commission in September 2019 at $77 billion to fund transportation projects from 2020 through 2029; this2023 is an increase from $75 billion in 2019 and more than double$2.7 billion. Given that the fiscal year 2016 level, which2023 appropriations bill for transportation was passed in February 2022, prior to resolution of the Proposition 1 and Proposition 7federal appropriations process, the current budget may not fully incorporate increased federal funding initiatives discussed in further detail below. The funding available in any given year is separate and distinct from lettings, orunder the process of providing notice, issuing proposals, receiving proposals, and awarding contracts. In December 2019, TXDOT updated itsIIJA.

For fiscal year 2020 lettings estimate to $7.3 billion from $8.9 billion and updated its fiscal year 2021 estimate to $14.2 billion. Longer-term, TXDOT has indicated a target of $8 billion per year in2023, total state and local lettings.

In February 2018, the federal government approved approximately $89 billion in relief funding related to a series of natural disasters, including Hurricane Harvey, which impacted the Houston market in the second half of 2017.  Furthermore, in June 2019, Congress passed an additional $19.1 billion disaster aid package and released more than $4 billion to Texas that Congress originally allocated in early 2018. At the state-level, between December 2018 and January 2019, the Texas Land Commission and the City of Houston announced two federally funded programs, totaling $2.27 billion, to assist homeowners affected by Hurricane Harvey; and in July 2019, the Governor signed four bills aimed at improving the state’s emergency preparedness and disaster relief programs, including a framework that provides more than $1.6 billionprojected expenditures for flood control projects and repairs across the state.  We believe that the federal and state-level funding stemming from these legislative actions will drive significant new water and transportation infrastructure construction in the Houston market over the coming years.
In November 2015, Texas voters approved the ballot measure known as Proposition 7, authorizing a constitutional amendment for transportation funding. The amendment dedicates a portion of the state’s general sales and use taxes and motor vehicle sales and rental taxes to the State Highway Fund (“SHF”) for use on non-tolled projects. Beginning in September 2017 (fiscal year 2018), if general state sales and use tax revenue exceeds $28 billion in a fiscal year, the next $2.5 billion will be directed to the SHF. Additionally, beginning in September 2019 (fiscal year 2020), if state motor vehicle sales and rental tax revenue exceeds $5 billion in a fiscal year, 35% of the amount above $5 billion will be directed to the SHF. In fiscal year 2018 sales tax revenue exceeded $30.5 billion, and as such, fiscal year 2019 was the first year in which the full Proposition 7 funding potential, $2.5 billion, was transferred to the SHF. As of November 2019, the Texas Office of the Comptroller expects over $2.5 billion per annum to be transferred to the SHF in both fiscal year 2020 and 2021.
In November 2014, Texas voters approved a ballot measure known as Proposition 1, which authorized a portion of the severance taxes on oil and natural gas to be redirected to the SHF each year. Fiscal year 2019 funding from Proposition 1 was $1.4 billion, up from $734 million in fiscal year 2018 and as of November 2019, the Texas Office of the Comptroller estimated its fiscal year 2020 Proposition 1 transfer to be $1.7 billion. Furthermore, in June 2019, the Texas State Legislature extended the sunset period on Proposition 1 to 2034 from 2024.

Utah’s transportation investment fund has $2.3 billion programmed for 2017 through 2022. In early 2017, Utah’s governor signed into law a measure to allow the state to issue up to $1 billion in highway general obligation bonds to accelerate funding for several projects that the Utah Transportation Commission already approved.  Furthermore, in January 2019, Utah’s Transportation Governance and Funding Task Force, appointed by the state legislature in 2017, released draft legislation that would increase fees on electric and hybrid vehicles and create a hotel room tax and local option sales tax to aid in transit development. The proposal would also authorize the Utah Department of Transportation to begin a study on a road usage charge pilot program.  In December 2019, Utah’s Governor signed a
Table of Contents

measure that beginning in April 2020 will impose a 4.85% state sales tax to gasoline purchases and increase the state diesel tax by 6 cents-per-gallon, with an additional 4 cents-per-gallon diesel tax increase in 2022. The tax is estimated to generate an additional $170 million for transportation investment in 2021.
In May 2010, Kansas passed a 10-year $8.2 billion highway bill. In May 2018, a legislative task force was convened to evaluate the current transportation system’s condition and funding of the state’s transportation system. The task force released its formal report in January 2019, concluding that it is imperative that the State of Kansas provides consistent, stable funding in order to maintain a quality transportation system; highlighting the negative impacts of $2.1 billion in transfers out of the SHF since 2011; and recommending that the state legislature review new potential sources of additional funding, including increasing registration fees, motor fuels taxes and fees for oversize vehicles and implementing new fees specific to alternative-fuel vehicles.  Based on the task force’s recommendations, in March 2019, the Kansas State Legislature approved the Governor’s fiscal year 2020 budget with $1.5 billion in transportation funding, a 32% increase from the $1.1 billion in fiscal year 2019, with the further plan to eliminate all transfers out of the SHF by 2023, starting with a $108 million reduction in fiscal year 2020 transfers. The elimination of transfers out of the SHF is expected to help pave the way for the issuance of new bonds for transportation projects. Furthermore, within the Kansas Department of Transportation (“KDOT”)are $2.2 billion, a 25.4% increase over fiscal 2022. Projected construction expenditures total $1.3 billion, a 29.2% annual increase.

The state budget the highway program was allocated $546 million, an increase of 138% or $317 million from fiscal year 2017. Most recently, the Governor authorized an additional $216 million in sales tax revenue to remain in the SHF in fiscal year 2020 to help restore the bridge replacement program and KDOT pledged to complete $435 million worth of transportation projects promised under the Transportation Works program by fiscal year 2023. KDOT has scheduled the following projects for the Missouri Department of Transportation Works program over the next three fiscal years: five projects in fiscal year 2021 for approximately $135 million, ten projects inbudget grew 11% between fiscal year 2022 for approximately $221 million and four projects in fiscal year 2023, for approximately $47 million.from $3.1 billion to $3.5 billion.
In July 2019, the Missouri Highways and Transportation Commission approved the 2020 Statewide Transportation Improvement Program (“STIP”), which increased funding to $4.6 billion for highway and bridge construction through 2024 from $4.5 billion in the 2019 STIP and $4.2 billion in the 2018 STIP. Most recently, Missouri lawmakers proposed four new bills aimed at increasing the motor fuel tax, although three of which would require statewide votes. The fourth bill (House Bill 1433), which does not require a statewide vote, includes a $450 million bond directed toward repairing road infrastructure and would increase the motor fuel tax from 17 cents-per-gallon to 19 cents-per-gallon from January 2021 until December 2030 and then decrease back to 18 cents-per-gallon thereafter. The increased motor fuel tax is expected to generate around $60 million per year to pay off the bond over a 10-year period.

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
Table of Contents

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.

We are subject to commodity price risk with respect to price changes in liquid asphalt and energy, including fossil fuels and electricity for aggregates, cement, ready-mix concrete and asphalt paving mix production, natural gas for hot mix asphalt production and diesel fuel for distribution vehicles and production related mobile equipment. Liquid asphalt escalator provisions in most of our private and commercial contracts limit our exposure to price fluctuations in this commodity. We often obtain similar escalators on public infrastructure contracts. In addition, as we seek to manage our risk to increasing energy prices, we enter into various firm purchase commitments, with terms generally less than one year, for certain raw materials.

Components of Operating Results
 
Total Revenue
 
We derive our revenue predominantly by selling construction materials and products and providing paving and related services. Construction materials consist of aggregates and cement. Products consist of related downstream products, including ready-mix concrete, asphalt paving mix and concrete products. Paving and related services that we provide are primarily asphalt paving services.
 
Revenue derived from the sale of construction materials areis recognized when risks associated with ownership have passed to unaffiliated customers. Typically this occurs when products are shipped. Product revenue generally includes sales of aggregates, cement and related downstream products and other materials to customers, net of discounts or allowances and taxes, if any.
 
Revenue derived from paving and related services areis recognized onusing a method similar to the percentage-of-completion basis,method, measured by the cost incurred to date compared to estimated total cost of each project. This method is used because management considers cost incurred to be the best available measure of progress on these contracts. Due to the inherent uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change over the life of the contract.
 
Operating Costs and Expenses
 
The key components of our operating costs and expenses consist of the following:
 
Cost of Revenue (excluding items shown separately)
 
Cost of revenue consists of all direct production and delivery costs and primarily includes labor, repair and maintenance, utilities, raw materials, fuel, transportation, subcontractor costs, royalties and other direct costs incurred in the production and delivery of our products and services.royalties. Our cost of revenue is directly affected by fluctuations in commodity energy prices, primarily diesel fuel, liquid asphalt and other petroleum-based resources. As a result, our operatingadjusted cash gross profit margins can be significantly affected by changes in the underlying cost of certain raw materials if they are not recovered through corresponding changes in revenue. We attempt to limit our exposure to changes in commodity energy prices by entering into forward purchase

commitments when appropriate. In addition, we have sales price adjustment provisions that provide for adjustments based on fluctuations outside a limited range in certain energy-related production costs. These provisions are in place for most of our public infrastructure contracts, and we seek to include similar price adjustment provisions in our private contracts.

General and Administrative Expenses
 
General and administrative expenses consist primarily of salaries and personnel costs, including stock-based compensation charges, for our sales and marketing, administration, finance and accounting, legal, information systems, human resources and certain managerial employees. Additional expenses include audit, consulting and professional fees, travel, insurance, rental costs, property taxes and other corporate and overhead expenses.
 
Depreciation, Depletion, Amortization and Accretion
 
Our business is capital intensive. We carry property, plant and equipment on our balance sheet at cost, net of applicable depreciation, depletion and amortization. Depreciation on property, plant and equipment is computed on a straight-line basis or based on the economic usage over the estimated useful life of the asset. The general range of depreciable lives by category, excluding mineral reserves, which are depleted based on the units of production method on a site-by-site basis, is as follows:

Landfill airspace and improvements10 - 30years

Amortization expense is the periodic expense related to leasehold improvements and intangible assets. The intangible assets were recognized with certain acquisitions and are generally amortized on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the lesser of the life of the underlying asset or the remaining lease term.
 
Accretion expense is the periodic expense recorded for the accrued mining reclamation liabilities and landfill closure and post-closure liabilities using the effective interest method.
Transaction Costs
Transaction costs consist primarily of third party accounting, legal, valuation and financial advisory fees incurred in connection with potential acquisitions.

Results of Operations

The following discussion of our results of operations is focused on the key financial measures we use to evaluate the performance of our business from both a consolidated and operating segment perspective. Operating income and margins are discussed in terms of changes in volume, pricing and mix of revenue source (i.e., type of product sales or service revenue). We focus on operating margin, which we define as operating income as a percentage of net revenue, as a key metric when assessing the performance of the business, as we believe that analyzing changes in costs in relation to changes in revenue provides more meaningful insight into the results of operations than examining costs in isolation.
 
Operating income (loss) reflects our profit from continuing operations after taking into consideration cost of revenue, general and administrative expenses, depreciation, depletion, amortization and accretion and transaction costs.gain on sale of property, plant and equipment. Cost of revenue generally increases ratably with revenue, as labor, transportation costs and subcontractor costs are recorded in cost of revenue. In periods where our revenue growth occurs primarily through acquisitions, general and administrative expenses and depreciation, depletion, amortization and accretion have historically grown ratably with revenue. However, as organic volumes increase, we expect these costs, as a percentage of revenue, to decrease. General and administrative expenses as a percentage of revenue vary throughout the year due to the seasonality of our business. Our transaction costs fluctuate withbusiness, and may also be impacted by acquisition and divestiture activities, depending on the levelsize of the business acquired or divested. During 2022, our general and administrative expenses were not materially impacted by our acquisition activity each year.or divestiture activity.

Operating income increased by $16.0 million in 2022 as compared to 2021, as inflationary increases in cost of revenue, increased repair and maintenance costs from sourcing constraints and higher subcontracting costs were more than offset by revenue growth, lower general and administrative expenses resulting from adjustments to estimates of health care and short term incentive amounts, and a decrease of $28.9 million in depletion, amortization and accretion expenses as a result of our divestitures.
 
For the year ended December 28, 2019, our net revenue growth was $27.0 million and $94.4 million from acquisitions and organic revenue, respectively. In addition, operating income increased by $51.1 million in 2019 as compared to 2018 primarily as our volume and pricing gains exceeded the increases of our costs of revenue, including increases in our general and administrative expenses and depreciation, depletion, amortization and accretion expense resulting from our acquisition program. Our depreciation, depletion, amortization and accretion increased $12.2 million largely due to acquisitions completed in 2019 and 2018.
For the year ended December 28, 2019,31, 2022, our operating margin percentage increased from 8.5%11.3% to 10.5% as12.1% compared to the year ended December 29, 2018,January 1, 2022, due to the items noted above.

Revenue from aggregates increased $103.8 million for the year ended December 28, 2019 as compared to the year ended December 29, 2018, due to increased volumes and improved average sales prices. Aggregate volumes growth was attributable primarily to organic growth in both the West and East segments, and to a lesser extent, our acquisition program. Organic aggregate volumes increased 9.5% as compared to 2018, primarily due to increases in Missouri, Kansas and Texas markets. Aggregate pricing of $10.99 per ton increased 7.0% as compared to 2018, supported by strong increases in Missouri.
Gross revenue from cement increased $12.0$2.5 million in the year ended December 28, 201931, 2022. We had strong price increases which were mostly offset by decreased aggregate volumes. Aggregate average sales prices of $12.07 per ton increased 8.2% in 2022 as compared to 2021, primarily due to a combination of inflation-justified price increases and an ongoing focus to improve customer mix. Organic aggregate volumes decreased 3.6% in 2022 as compared to 2021, primarily due to moderating demand, as well as unfavorable weather conditions in certain geographies, partially offset by increases in our Virginia and Georgia markets.
Revenue from cement increased $48.8 million in the year ended December 29, 2018. The increase was primarily due to31, 2022.

Gain on Sale of Businesses

We continue to make progress on our strategy to divest certain businesses through portfolio optimization. In 2022, we sold three businesses in the East segment, resulting in cash proceeds of $373.1 million and a net gain on disposition of businesses of $172.4 million. In 2021, we sold seven businesses in the East segment and one business in the West segment, resulting in total cash proceeds of $128.3 million and a net gain on disposition of businesses of $20.0 million.

Tax Receivable Agreement Expense (Benefit) Expense
 
Our TRA expense (benefit) for the yearyears ended December 28, 201931, 2022 and January 1, 2022 was $16.2$1.6 million as compared to TRA benefit of $22.7and $(6.8) million, in the year ended December 29, 2018.respectively. Each year, we update our estimate as to when TRA payments will be made. When payments are made under the TRA, a portion of the payment made will be characterized as imputed interest under IRS regulations. The TCJA enacted in late 2017 contained provisions whereby interest expense deductions may be limited, and the IRS issued proposed regulations in late 2018 around the deductibility of interest expense. Under our forecast prepared at the end of 2018, we expected the amount of imputed interest based on future TRA payments would be limited under the proposed IRS regulations, and therefore we would not benefit from that deduction. Based on our forecast model updated at the end of 2019, which updated our forecast of the timing of TRA payments, we believe our interest expense deductions will not be limited under the proposedInternal Revenue Service ("IRS") regulations. We also updated our estimate of the state income tax rate that will be in effect at the date the TRA payments are made. As a result of updated state income tax rate, and the imputed interest limitationtiming of expected utilization of attributes noted above, we increasedadjusted our TRA liability by $16.2 million as of December 28, 2019 and reduced our TRA liability by $22.7 million as of December 29, 2018.the amounts noted above.

The Company's income tax provision is calculated under the provisions of the proposed regulations related to tax reform legislation, which may limit our ability to deduct interest expense in calculating our taxable income. Once the final regulations are issued, the Company will adjust its calculations, if necessary.
 
As of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, Summit Inc. had a valuation allowance of $1.7$1.1 million and $19.4$1.7 million against our deferred tax assets, respectively.

Net revenue in the West segment increased $11.6$102.6 million forin the year ended December 28, 201931, 2022, due to net revenue increases across all lines of business. Organic aggregate volumes decreased 1.3% in 2022 as compared to December 29, 2018, primarily due to increases in net revenues from aggregates and asphalt, offset by a decrease in paving and related services as well as a decrease in other revenues due to the sale of a non-core business in the third quarter of 2018. Organic aggregate volumes increased 5.8% in 2019 as compared to 2018, and2021, while organic aggregates average sales prices increased 2.7%.10.4%, as price increases were implemented across all geographies to help offset inflationary factors. Organic ready-mix concrete volumes were down 1.5%, while we achieved a 3.6% increase indecreased 4.2% and our organic ready-mix concrete average sales prices.prices increased 14.3%. Construction activity appears to be slowing, to varying degrees, across residential markets, including in our two largest, Houston and Salt Lake City, as home builders anticipate lower demand due to higher interest rates and inflationary pressures. We continue to monitor that activity given increases in mortgage rates and other inflationary concerns that impact residential markets.
 
The West segment’s operating income increased $17.1$10.7 million in 2019 as compared to 2018 as our revenue gains as described above outpaced increases in labor costs and hydrocarbon costs included in cost of revenue and increases in general and administrative expenses, as well as higher levels of depreciation and amortization from acquisitions made in 2018. Further, wetter weather conditions in our Texas markets had a negative effect on our operational efficiencies during 2018. Adjusted EBITDA increased $16.0$9.0 million in 2019 as compared to 2018the year ended December 31, 2022. The increases in operating income and Adjusted EBITDA in 2022 occurred primarily due to the items noted above, offset by tighter construction marginsincreases in our Texasaverage sales prices for aggregates and Utah markets.ready-mix concrete. The operating margin percentage in the West segment increaseddecreased slightly in 2019 to 10.7%2022 as compared to 9.1% in 20182021, due to higher pricing and volume gains which exceeded increased labor costs, depreciation and amortization,the aggregate product mix in Texas as well as increases in general and administrative expenses resulting from acquisitions that occurred in 2018 and 2019.ongoing input cost inflation.

Liquidity and Capital Resources

Our primary sources of liquidity include cash on-hand, cash provided by our operations, and amounts available for borrowing under our senior secured credit facilities and capital-raising activities in the debt and capital markets. In addition to our current sources of liquidity, we have access to liquidity through public offerings of shares of our Class A common stock. To facilitate such offerings, in January 2020,2023, we filed a shelf registration statement with the SEC that is effective for a term of three years and will expire in January 2023.2026. The amount of Class A common stock to be issued pursuant to this shelf registration statement was not specified when it was filed and there is no specific limit on the amount we may issue. The specifics of any future offerings, along with the use of the proceeds thereof, will be described in detail in a prospectus supplement, or other offering materials, at the time of any offering.
 
As of December 28, 2019,31, 2022, we had $311.3$520.5 million in cash and cash equivalents and $497.0$762.5 million of working capital as compared to $128.5$381.0 million and $330.9$560.5 million, respectively, at December 29, 2018.January 1, 2022. Working capital is calculated as current assets less current liabilities. There were no restricted cash balances as of December 28, 201931, 2022 or December 29, 2018.January 1, 2022.
 
Our remaining borrowing capacity on our $345.0 million senior secured revolving credit facility as of December 28, 201931, 2022 was $329.8$325.2 million, which is net of $15.2$19.8 million of outstanding letters of credit, and is fully available to us within the terms and covenant requirements of our credit agreement. In January 2023, we amended our senior secured revolving credit facility, increasing the total availability to $395.0 million and extending the maturity date to January 2028.

In March 2022, our Board of Directors authorized a share repurchase program, whereby we can repurchase up to $250.0 million of our Class A common stock. During the first nine months of 2022, we repurchased 3.4 million shares of Class A common stock for $101.0 million. As of December 31, 2022, approximately $149.0 million remained available for share repurchases under the share repurchase program.
 
Given the seasonality of our business, we typically experience significant fluctuations in working capital needs and balances throughout the year. Our working capital requirements generally increase during the first half of the year as we build up inventory and focus on repair and maintenance and other set-up costs for the upcoming season. Working capital levels then decrease as the construction season winds down and we enter the winter months, which is when we see significant inflows of cash from the collection of receivables.

Our acquisition strategy has historically required us to raise capital through equity issuances or debt financings. As of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, our long-term borrowings totaled $1.9$1.5 billion and $1.8$1.6 billion, respectively, for which we incurred $102.0$77.0 million and $102.7$80.3 million of interest expense, respectively. Our senior secured revolving facility has been adequate to fund our seasonal working capital needs and certain acquisitions. We had no outstanding borrowings on the revolving credit facility as of December 28, 2019.31, 2022.

For details regarding certain other material cash requirements from known contractual and other obligations see “—Contractual Obligations” below.

During 2022, we also received $373.1 million in proceeds from divestitures as part of our Elevate Summit strategy. Management will continue to optimize the portfolio, which could include future divestitures.

We believe we have access to sufficient financial resources from our liquidity sources to fund our business and operations, including contractual obligations, capital expenditures and debt service obligations, for at least the next twelve months. Our growth strategy contemplates future acquisitions for which we believe we have sufficient access to capital. We also plan to divest of certain dilutive businesses as we rationalize our portfolio, which will also generate additional capital.

As market conditions warrant we may, from time to time, seek to purchase our outstanding debt securities or loans, including Senior Notes and borrowings under our senior secured credit facilities. Such transactions could be privately

negotiated, open market transactions, tender offers or otherwise. Subject to any applicable limitations contained in the agreements governing our indebtedness, any purchases made by us may be funded by the use of cash on our balance sheet or the incurrence of new secured or unsecured debt. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material. Any such purchases may equate to a substantial amount of a particular class or series of debt, which may reduce the trading liquidity of such class or series.
 
Our Long-Term Debt
 
Please refer to the notes to the consolidated financial statements found elsewhere in this report for detailed information regarding our long-term debt and senior secured revolving credit facility, scheduled maturities of long-term debt and affirmative and negative covenants. Among other things, we are required to maintain a Consolidated First Lien Net Leverage Ratio that is no greater than 4.75 to 1.00. Our first lien net leverage ratio, for purposes of this maintenance requirement, is calculated following each quarter based on information for the most recently ended four fiscal quarters for which internal financial information is available by dividing our Consolidated First Lien Net Debt as of the end of such period by our Consolidated EBITDA for such period. Consolidated EBITDA for purposes of our senior secured credit facility is calculated in accordance with our presentation of Further Adjusted EBITDA below. We define Further Adjusted EBITDA as Adjusted EBITDA plus transaction costs and the EBITDA contribution of certain recent acquisitions.
 
For the years ended December 28, 201931, 2022 and December 29, 2018,January 1, 2022, our Consolidated First Lien Net Leverage Ratio was 0.800.01 to 1.00 and 1.350.50 to 1.00, respectively, based on consolidated first lien net debt of $369.4$3.2 million and $551.2$261.6 million as of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively, divided by Further Adjusted EBITDA of $461.5$493.0 million and $408.4$520.3 million for the years ended December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively. As of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, we were in compliance with all debt covenants.

The following table sets forth a reconciliation of net income to Adjusted EBITDA and Further Adjusted EBITDA for the periods indicated. Adjusted EBITDA and Further Adjusted EBITDA are not U.S. GAAP measures and should not be considered in isolation, or as a substitute for our results as reported under U.S. GAAP.

Cash Paid for Capital Expenditures

We estimate that we will invest between $185$220 million and $205$240 million in capital expenditures in 2020,2023, which includes $65 - $80 million for our greenfield development projects. The timing of our greenfield expenditures is dependent upon the timing of when permits may be issued. We expect to fund our capital expenditure program through cash on hand, cash from operations, outside financing arrangements and available borrowings under our revolving credit facility.
 
Tax Receivable Agreement
 
Exchanges of LP Units for shares of Class A common stock are expected to result in increases in the tax basis of the tangible and intangible assets of Summit Holdings. These increases in tax basis may increase (for tax purposes) depreciation and amortization deductions and therefore reduce the amount of tax that Summit Inc. would otherwise be required to pay in the future. In connection with the IPO, we entered into a TRA with the holders of LP Units that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result of these increases in tax basis and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA. The increases in tax basis as a result of an exchange of LP Units for shares of Class A common stock, as well as the amount and timing of any payments under the TRA, are difficult to accurately estimate as they will vary depending upon a number of factors, including:
 
the timing of exchanges—for instance, the increase in any tax deductions will vary depending on the fair market value, which may fluctuate over time, of the depreciable or amortizable assets of Summit Holdings at the time of each exchange;

the price of shares of our Class  A common stock at the time of the exchange—the increase in any tax deductions, as well as the tax basis increase in other assets, of Summit Holdings, is directly proportional to the price of shares of our Class A common stock at the time of the exchange;

the extent to which such exchanges are taxable—if an exchange is not taxable for any reason, increased deductions will not be available;

���
the amount and timing of our income—Summit Inc. is required to pay 85% of the cash tax savings as and when realized, if any. If Summit Inc. does not have taxable income, Summit Inc. is not required (absent a change of control or circumstances requiring an early termination payment) to make payments under the TRA for that taxable year because no cash tax savings will have been realized. However, any tax attributes that do not result in realized benefits in a given tax year will likely generate tax attributes that may be utilized to generate benefits in previous or future tax years. The utilization of such tax attributes will result in cash tax savings that will result in payments under the tax receivable agreement; and

the effective tax rate – The benefit that Summit Inc. realizes is dependent on the tax rate in effect at the time taxable income is generated.

We anticipate funding payments under the TRA from cash flows from operations, available cash and available borrowings under our Senior Secured Revolving Credit Facilities. As of December 28, 2019,31, 2022, we had accrued $327.0$328.4 million as TRA liability. The entireOf the total TRA liability, $0.5 million is a long term liability as no additional payments are expected to be paid in the next twelve months.
 
In addition, the TRA provides that upon certain changes of control, Summit Inc.’s (or its successor’s) obligations would be based on certain assumptions, including that Summit Inc. would have sufficient taxable income to fully utilize the deductions arising from tax basis and other tax attributes subject to the TRA. With respect to our obligations under the TRA relating to previously exchanged or acquired LP Units and certain net operating losses, we would be required to make a payment equal to the present value (at a discount rate equal to one year LIBOR plus 100 basis points) of the anticipated future tax benefits determined using assumptions (ii) through (v) of the following paragraph.
 
Furthermore, Summit Inc. may elect to terminate the TRA early by making an immediate payment equal to the present value of the anticipated future cash tax savings. In determining such anticipated future cash tax savings, the TRA includes several assumptions, including that (i) any LP Units that have not been exchanged are deemed exchanged for the market value of the shares of Class A common stock at the time of termination, (ii) Summit Inc. will have sufficient taxable income in each future taxable year to fully realize all potential tax savings, (iii) Summit Inc. will have sufficient taxable income to fully utilize any remaining net operating losses subject to the TRA on a straight line basis over the shorter of the statutory expiration period for such net operating losses or the five-year period after the early termination or change of control, (iv) the tax rates for future years will be those specified in the law as in effect at the time of termination and (v) certain non-amortizable assets are deemed disposed of within specified time periods. In addition, the present value of such anticipated future cash tax savings are discounted at a rate equal to LIBOR plus 100 basis points.
 
As a result of the change in control provisions and the early termination right, Summit Inc. could be required to make payments under the TRA that are greater than or less than the specified percentage of the actual cash tax savings that Summit Inc. realizes in respect of the tax attributes subject to the TRA (although any such overpayment would be taken into account in calculating future payments, if any, under the TRA) or that are prior to the actual realization, if any, of such future tax benefits. Also, the obligations of Summit Inc. would be automatically accelerated and be immediately due and payable in the event that Summit Inc. breaches any of its material obligations under the agreement and in certain events of bankruptcy or liquidation. In these situations, our obligations under the TRA could have a substantial negative impact on our liquidity.
 
Under the terms of the TRA, we can terminate the TRA at any time, which would trigger a cash payment to the pre-IPO owners. Based upon a $23.84$28.39 per share price of our Class A common stock, the closing price of our stock on December 28, 201931, 2022 and a contractually defined discount rate of 3.00%6.48%, we estimate that if we were to exercise our right to terminate the TRA, the aggregate amount required to settle the TRA would be approximately $289$249 million.

Commitments and Contingencies
 
We are party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded when the outcome is probable and can be reasonably estimated. 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 position, results of operations or liquidity. We record legal fees as incurred.

In March 2018, we were notified of an investigation by the CCB into pricing practices by certain asphalt paving contractors in British Columbia, including 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 Remediation and Site Restoration—Our operations are subject to and affected by federal, state, provincial and local laws and regulations relating to the environment, health and safety and other regulatory matters. These operations require environmental operating permits, which are subject to modification, renewal and revocation. We regularly monitor and review its operations, procedures and policies for compliance with these laws and regulations. Despite these compliance efforts, risk of environmental liability is inherent in the operation of our business, as it is with other companies engaged in similar businesses and there can be no assurance that environmental liabilities and noncompliance will not have a material adverse effect on our consolidated financial condition, results of operations or liquidity.

Other—We are obligated under various firm purchase commitments for certain raw materials and services that are in the ordinary course of business. Management does not expect any significant changes in the market value of these goods and services during the commitment period that would have a material adverse effect on the financial condition, results of operations, and cash flows of the Company. The terms of the purchase commitments generally approximate one year.

Off-Balance Sheet Arrangements
 
As of December 28, 2019,31, 2022, we had no material off-balance sheet arrangements.

Non-GAAP Performance Measures
 
We evaluate our operating performance using metrics that we refer to as “Adjusted EBITDA,” “Adjusted EBITDA Margin,” “Adjusted Cash Gross Profit” and “Adjusted Cash Gross Profit Margin” which are not defined by U.S. GAAP and should not be considered as an alternative to earnings measures defined by U.S. GAAP. We define Adjusted EBITDA as EBITDA, adjusted to exclude accretion, loss on debt financings, loss from discontinued operationsgain on sale of business, non-cash compensation and certain other non-cash and non-operating items. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by net revenue. We define Adjusted Cash Gross Profit as operating income before general and administrative expenses, depreciation, depletion, amortization and accretion and transaction costs and Adjusted Cash Gross Profit Margin as Adjusted Cash Gross Profit as a percentage of net revenue.

We present Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit and Adjusted Cash Gross Profit Margin for the convenience of investment professionals who use such metrics in their analyses. The investment community often uses these metrics to assess the operating performance of a company’s business and to provide a consistent comparison of performance from period to period. We use these metrics, among others, to assess the operating performance of our individual segments and the consolidated company.

Non-GAAP financial measures are not standardized; therefore, it may not be possible to compare such financial measures with other companies’ non-GAAP financial measures having the same or similar names. We strongly encourage investors to review our consolidated financial statements in their entirety and not rely on any single financial measure.

The tables below reconcile our net income (loss) to EBITDA and Adjusted EBITDA, and present Adjusted EBITDA by segment and reconcile operating income to Adjusted Cash Gross Profit for the periods indicated:

Critical Accounting Policies and Estimates
 
Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period.
 
Table of Contents

On an ongoing basis, management evaluates its estimates, including those related to the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, pension and other postretirement obligations and asset retirement obligations. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Acquisitions—Purchase Price Allocation
 
We regularly review strategic long-term plans, including potential investments in value-added acquisitions of related or similar businesses, which would increase our market share and/or are related to our existing markets. When an acquisition is completed, our consolidated statement of operations includes the operating results of the acquired business starting from the date of acquisition, which is the date that control is obtained. The purchase price is determined based on the estimated fair value of assets given to and liabilities assumed from the seller as of the date of acquisition. We allocate the purchase price to the estimated fair values of the tangible and intangible assets acquired and liabilities assumed as valued at the date of acquisition. Goodwill is recorded for the excess of the purchase price over the net of the fair value of the identifiable assets acquired and liabilities assumed as of the acquisition date. The estimation of fair values of acquired assets and assumed liabilities is judgmental and requires various assumptions and the amounts and useful lives assigned to depreciable and amortizable assets compared to amounts assigned to goodwill, which is not amortized, can significantly affect the results of operations in the period of and periods subsequent to a business combination.
 
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction, and therefore represents an exit price. A fair value measurement assumes the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. We assign the highest level of fair value available to assets acquired and liabilities assumed based on the following options:
 
Level 1—Quoted prices in active markets for identical assets and liabilities.

Level 2—Observable inputs, other than quoted prices, for similar assets or liabilities in active markets.

Level 3—Unobservable inputs, which includes the use of valuation models.

Level 1 fair values are used to value investments in publicly-traded entities and assumed obligations for publicly-traded long-term debt.

Level 2 inputsfair values are typically used to estimate the fair value of acquired receivables, inventories, machinery equipment and equipment,, land, buildings, deferred income tax assets and assumedliabilities, liabilities for asset retirement obligations, environmental remediation and compliance obligations and contingencies.obligations.Additionally, Level 2 fair values are typically used to value assumed contracts at other-than-market rates.

Level 3 inputsfair values are used to value acquired mineral reserves and leased mineral interests and other identifiable intangible assets. The fair values of mineral reserves and leased mineral interests are determined using an excess earnings approach, which requires management to estimate future cash flows. The estimate of future cash flows is based on available historical information and forecasts determined by management, but is inherently uncertain. Key assumptions in estimating future cash flows include sales price, volumes and expected profit margins, net of capital requirements. The present value of the projected net cash flows represents the fair value of acquiredassigned to mineral reserves and mineral interestsinterests. The discount rate is a significant assumption used in the valuation model and separately-identifiable intangible assets.is based on the required rate of return that a hypothetical market participant would assume if purchasing the acquired business.
 
There is a measurement period after the acquisition date during which we may adjust the amounts recognized for a business combination. Any such adjustments are based on us obtaining additional information that existed at the acquisition date regarding the assets acquired or the liabilities assumed. Measurement period adjustments are generally recorded as increases or decreases to the goodwill recognized in the transaction. The measurement period ends once we have obtained all necessary information that existed as of the acquisition date, but does not extend beyond one year from the date of acquisition. Any adjustments to assets acquired or liabilities assumed beyond the measurement period are recorded in earnings.
 
We paid cash of $5.4$22.7 million and $246.0$19.5 million, net of cash acquired, in business combinations and allocated this amount to assets acquired and liabilities assumed during the years ended December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively.
 
Goodwill
 
Goodwill is tested annually for impairment and in interim periods if events occur indicating that the carrying amounts may be impaired. The evaluation involves the use of significant estimates and assumptions and considerable management judgment. Our judgments regarding the existence of impairment indicators and future cash flows are based on operational performance of our businesses, market conditions and other factors. Although there are inherent uncertainties in this assessment process, the estimates and assumptions we use, including estimates of future cash flows, volumes, market penetration and discount rates, are consistent with our internal planning. The estimated future cash flows are derived from internal operating budgets and forecasts for long-term demand and pricing in our industry and markets. If these estimates or their related
Table of Contents

assumptions change in the future, we may be required to record an impairment charge on all or a portion of our goodwill. Furthermore, we cannot predict the occurrence of future impairment-triggering events nor the affect such events might have on our reported values. Future events could cause us to conclude that impairment indicators exist and that goodwill associated with our acquired businesses are impaired. Any resulting impairment loss could have an adverse effect on our financial condition and results of operations.
 
The annual goodwill test is performed by first assessing qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If, as a result of the qualitative assessment, it is determined that an impairment is more likely than not, we are then requireda Step-1 approach is performed to perform the two-step quantitativequantitatively compare each reporting unit’s fair value to its carrying value. The Step-1 analysis fails when a report unit's carrying value is in excess of its fair value, resulting in an impairment test, otherwise further analysis is not required. We also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test. The ultimate outcome of the goodwill impairment review for a reporting unit should be the same whether we choose to perform the qualitative assessment or proceed directly to the two-step quantitative impairment test.loss.
 
Under the two-step quantitative impairment test, step oneStep-1 of the evaluation of impairment involves comparing the current fair value of each reporting unit to its carrying value, including goodwill. We use a discounted cash flow (“DCF”) model to estimate the current fair value of our reporting units when testing for impairment, as management believes forecasted cash flows are the best indicator of fair value. A number of significant assumptions and estimates are involved in the application of the DCF model to forecast operating cash flows, including macroeconomic trends in the reporting unit’s geographic area impacting private construction and public infrastructure industries, the timing of work embedded in our backlog, our performance and profitability under our contracts, our success in securing future sales and the appropriate interest rate used to discount the projected cash flows. We also perform a market assessment of our enterprise value. We believe the estimates and assumptions used in the valuations are reasonable.
 
In 2022, in conjunction with our annual review of goodwill on the first day of the fourth quarter, we performed the qualitative assessmentselected a Step-1 approach for our reporting units. In 2019, we performed a two-step quantitative analysis on all of our reporting units. Step 1 of that analysis compares the estimated the fair value of the reporting units using an income approach (i.e., a discounted cash flow technique) and a market approach to the carrying value of the reporting unit. If the estimated fair value exceeds its carrying value, the goodwill of the reporting unit is not considered impaired. If the carrying value of the reporting unit exceeds its fair value, we proceed to the second step to measure the amount of potential impairment loss.
As of December 28, 2019,31, 2022, we determined that no events or circumstances from October 1, 20193, 2022 through December 28, 201931, 2022 indicated that a further assessment was necessary.

Service Revenue Recognition
 
We earn revenue from the sale of products, which primarily include aggregates, cement, ready-mix concrete and asphalt, but also include concrete products and plastics components, and from the provision of services, which are primarily paving and related services, but also include landfill operations, the receipt and disposal of waste that is converted to fuel for use in our cement plants.

Products 

We earn revenue from the sale of products, which primarily include aggregates, cement, ready-mix concrete and asphalt, but also include concrete products, net of discounts or allowances, if any, and freight and delivery charges billed to customers. Freight and delivery charges associated with cement sales are recorded on a net basis together with freight costs within cost of sales. Revenue for product sales is recognized when evidence of an arrangement exists and when control passes, which generally is when the product is shipped. 

Aggregates and cement products are sold point-of-sale through purchase orders. When the product is sold on account, collectability typically occurs 30 to 60 days after the sale.  Revenue is recognized when cash is received from the customer at the point of sale or when the products are delivered or collected on site. There are no other timing implications that will create a contract asset or liability, and contract modifications are unlikely given the timing and nature of the transaction. Material sales are likely to have multiple performance obligations if the product is sold with delivery. In these instances, delivery most often occurs on the same day as the control of the product transfers to the customer. As a result, even in the case of multiple performance obligations, the performance obligations are satisfied concurrently and revenue is recognized simultaneously.

Revenue from the receipt of waste fuels is recognized when the waste is accepted and a corresponding liability is recognized for the costs to process the waste into fuel for the manufacturing of cement or to ship the waste offsite for disposal in accordance with applicable regulations.

Collectability of service contracts is due reasonably after certain milestones in the contract are performed. Milestones vary by project, but are typically calculated using monthly progress based on thea percentage of completion or a customer’s engineer review of progress. The majority of the time, collection occurs within 90 days of billing and cash is received within the same fiscal year as services performed. On most projects the customer will withhold a portion of the invoice for retainage which may last longer than a year depending on the job.

Revenue derived from paving and related services is recognized usingover time based on the percentageproportion of costs incurred to date relative to the total estimated costs at completion, method, which approximates progress towards completion. Under the percentage of completionthis method, we recognize paving and related services revenue as services are rendered. The majority of our construction service contracts are completed within one year, but may occasionally extend beyond this time frame. The majority of our construction service contracts, and therefore, revenue, are opened and completed within one year, with most activity during the spring, summer and fall. We estimate profit as the difference between total estimated revenue and total estimated cost of a contract and recognize that profit over the life of the contract based on input measures. We generally measure progress toward completion on long-term paving and related services contracts based on the proportion of costs incurred to date relative to total estimated costs at completion. We include revisions of estimated profits on contracts in earnings under the cumulative catch-up method, under which the effect of revisions in estimates is recognized immediately. If a revised estimate of contract profitability reveals an anticipated loss on the contract, we recognize the loss in the period it is identified. 

TheOur method, which is similar to the percentage of completion method of accounting, involves the use of various estimating techniques to project costs at completion, and in some cases includes estimates of recoveries asserted against the customer for changes in specifications or other disputes. Contract estimates involve various assumptions and projections relative to the outcome of future events over multiple periods, including future labor productivity and availability, the nature and complexity of the work to be performed, the cost and availability of materials, the effect of delayed performance, and the availability and timing of funding from the customer. These estimates are based on our best judgment. A significant change in one or more of these estimates could affect the profitability of one or more of our contracts. We review our contract estimates regularly to assess revisions in contract values and estimated costs at completion. Inherent uncertainties in estimating costs make it at least reasonably possible that the estimates used will change within the near term and over the life of the contracts. No material adjustments to a contract were recognized in the year ended December 28, 2019.31, 2022.

We recognize claims when the amount of the claim can be estimated reliably and its realizationit is probable.legally enforceable. In evaluating these criteria, we consider the contractual basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim.

When the contract includes variable consideration, we estimate the amount of consideration to which we will be entitled in exchange for transferring the promised goods or services to a customer. The amount of estimated variable consideration included in the transaction price is the amount for which it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Types of variable consideration include, but are not limited to, liquidated damages and other performance penalties and production and placement bonuses. 

The majority of contract modifications relate to the original contract and are often an extension of the original performance obligation. Predominately, modifications are not distinct from the terms in the original contract; therefore, they are considered part of a single performance obligation. We account for the modification using a cumulative catch-up adjustment. However, there are instances where goods or services in a modification are distinct from those transferred prior to the modification. In these situations, we account for the modifications as either a separate contract or prospectively depending on the facts and circumstances of the modification. 

Generally, construction contracts contain mobilization costs which are categorized as costs to fulfill a contract. These costs are excluded from any measure of progress toward contract fulfillment. These costs do not result in the transfer of control of a good or service to the customer and are amortized over the life of the contract.

Costs and estimated earnings in excess of billings are composed principally of revenue recognized on contracts on a method similar to the percentage of completion method for which billings had not been presented to customers because the amounts were not billable under the contract terms at the balance sheet date. In accordance with the contract terms, the unbilled receivables at the balance sheet date are expected to be billed in following periods. Billings in excess of costs and estimated earnings represent billings in excess of revenue recognized. Contract assets and liabilities are netted on a contract-by-contract basis.

Income Taxes
 
Summit Inc. is a corporation subject to income taxes in the United States. Certain subsidiaries, including Summit Holdings, or subsidiary groups of the Company are taxable separate from Summit Inc. The provisions for income taxes, or Summit Inc.’s proportional share of the provision, are included in the Company’s consolidated financial statements.
 
The Company’s deferred income tax assets and liabilities are computed for differences between the tax basis and financial statement amounts that will result in taxable or deductible amounts in the future. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible, as well as consideration of tax-planning strategies to determine whether we may seek to utilize any net operating loss carryforwards scheduled to expire in the near future. The estimates of future taxable income involves the use of significant estimates and assumptions and considerable management judgment. Our judgments regarding future taxable income and future cash flows are based on operational performance of our businesses, market conditions and other factors. Although there are inherent uncertainties in this assessment process, the estimates and assumptions we use, including estimates of future cash flows, are consistent with our internal planning. The computed deferred balances are based on enacted tax laws and applicable rates for the periods in which the differences are expected to affect taxable income. A valuation allowance is recognized for deferred tax assets if it is more likely than not that some portion or all of the net deferred tax assets will not be realized. In making such a determination, all available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines it would be able to realize its deferred tax assets for which a valuation allowance had been recorded, then an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
 
The Company evaluates the tax positions taken on income tax returns that remain open and positions expected to be taken on the current year tax returns to identify uncertain tax positions. Unrecognized tax benefits on uncertain tax positions are recorded on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50 percent likely to be realized is recognized. Interest and penalties related to unrecognized tax benefits are recorded in income tax benefit.expense (benefit).

Tax Receivable Agreement
 
Tax Receivable Agreement— When Summit Inc. purchases LP Units for cash or LP Units are exchanged for shares of Class A common stock, this results in increases in Summit Inc.’s share of the tax basis of the tangible and intangible assets of Summit Holdings, which increases the tax depreciation and amortization deductions that otherwise would not have been available to Summit Inc.  These increases in tax basis and tax depreciation and amortization deductions are expected to reduce the amount of cash taxes that we would otherwise be required to pay in the future. In connection with our IPO, we entered into a TRA with the holders of the LP Units and the pre-IPO owners that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. actually realizes (or, under certain circumstances such as an early termination of the TRA is deemed to realize) as a result of (i) these increases in tax basis and (ii) our utilization of certain net operating losses of the pre-IPO owners and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA.

We periodically evaluate the realizability of the deferred tax assets resulting from the exchange of LP Units for Class A common stock. Our evaluation considers all sources of taxable income; all evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, a valuation allowance is needed for some portion or all of the deferred tax assets. If the deferred tax assets are determined to be realizable, we then assess whether payment of amounts under the TRA have become probable. If so, we record a TRA liability of 85% of such deferred tax assets. In subsequent periods, we assess the realizability of all of our deferred tax assets subject to the TRA. Should we determine a deferred tax asset with a valuation allowance is realizable in a subsequent period, the related valuation allowance will be released and consideration of a corresponding TRA liability will be assessed. The realizability of deferred tax assets, including those subject to the TRA, is dependent upon the generation of future taxable income during the periods in which those deferred tax assets become deductible and consideration of prudent and feasible tax-planning strategies.

The measurement of the TRA liability is accounted for as a contingent liability. Therefore, once we determine that a payment to a pre-IPO owner has become probable and can be estimated, the estimate of payment will be accrued.

New Accounting Pronouncements Not Yet Adopted
In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which reduces the accounting complexity for implementing a cloud computing arrangement. The ASU aligns with the capitalization of implementation costs among hosting arrangements and costs incurred to develop internal-use software. The ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. We are compiling a list of contracts and are beginning to assess the impact of adopting this ASU.

In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework Changes to The Disclosure Requirements for Defined Benefits Plans, which modifies the disclosure requirements of employer-sponsored defined benefit and other postretirement benefits plans. The ASU is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. Early adoption is permitted. We are evaluating the additional disclosure requirements and beginning to assess the impact of adopting this ASU.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
 
We are exposed to certain market risks arising from transactions that are entered into in the normal course of business. Our operations are highly dependent upon the interest rate‑sensitive construction industry as well as the general economic environment. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs. Management has considered the current economic environment and its potential effect to our business. Demand for materials‑based products, particularly in the residential and nonresidential construction markets, could decline if companies and consumers are unable to obtain financing for construction projects or if an economic recession causes delays or cancellations to capital projects. Additionally, in preceding years, declining tax revenue, state budget deficits and unpredictable or inconsistent federal funding have negatively affected states’ abilities to finance infrastructure construction projects.
 
Commodity and Energy Price Risk

We are subject to commodity price risk with respect to price changes in liquid asphalt and energy, including fossil fuels and electricity for aggregates, cement, ready‑mix concrete and asphalt paving mix production, natural gas for hot mix asphalt production and diesel fuel for distribution vehicles and production related mobile equipment. Liquid asphalt escalators in most of our public infrastructure contracts limit our exposure to price fluctuations in this commodity, and we seek to obtain escalators on private and commercial contracts. Similarly, in periods of decreasing oil prices, a portion of the cost savings will be recouped by our end customers. Changes in oil prices also could affect demand in certain of our markets, particularly in Midland/Odessa, Texas and indirectly in Houston, Texas, which collectively represented approximately 12.7%15.7% of our consolidated revenue in 2019.2022. In addition, we enter into various firm purchase commitments, with terms generally less than one year, for certain raw materials.
 
For the year ended December 28, 2019,31, 2022, our costs associated with liquid asphalt and energy amounted to approximately $275.0$282.2 million. Accordingly, a 10% increase or decrease in the total cost of liquid asphalt and energy would have decreased or increased, respectively, our operating results for the year by approximately $27.5$28.2 million. However, this does not take into consideration liquid asphalt escalators in certain contracts or forward purchase commitments put into place before December 28, 2019.31, 2022.

Inflation Risk

Inflation rates in recent years have notAlthough there has been a significant factorincrease in our revenue or earningsinflation recently, it has not had a substantial impact due to relatively low inflation and our ability to recover increasing costs by obtaining higher prices for our products, including sale price escalators in place for most public infrastructure sector contracts. Inflation risk varies with the level of activity in the construction industry, the number, size and strength of competitors and the availability of products to supply a local market. We continue to monitor inflationary impacts in our business, primarily labor, energy and raw materials, with the goal of passing along price increases to our customers to mitigate the full effect of inflation.
 
Foreign Currency Risk
 
In 2014, we expanded our operations into Canada with the acquisition of Mainland. With this expansion, we became subject to foreign currency risk related to changes in the U.S. dollar/Canadian dollar exchange rates. A 10% adverse change in foreign currency rates from December 20182022 levels would not have had a material effect on our financial condition, results of operations or liquidity.

Interest Rate Risk
 
As of December 28, 2019,31, 2022, we had $624.3$509.6 million in term loans outstanding which bear interest at a variable rate. As of December 28, 2019,31, 2022, the rate in effect was the one‑month LIBORSOFR of 1.70%4.51%, plus the Applicable Ratea floor of 200 basis points.3.00% and 0.10% SOFR adjustment rate. Therefore, a 100 basis point increase in the interest rate at December 28, 201931, 2022 would only have increased the all-in rate from 3.70%7.61% to 4.70%8.61%, the effect of which would have been an increase of $6.2$5.1 million on annual interest expense.

On January 19, 2017, we amended the Credit Agreement and, as a result, the floor decreased from 1.00% to 0.75% and the applicable margin was reduced. On November 21, 2017, Summit LLC entered into Amendment No. 2 to the Amended and Restated Credit Agreement, which, among other things, extended the maturity date from 2022 to 2024, brought the floor to zero and reduced the applicable margin in respect

Table of the $635.4 million outstanding principal amount of term loans thereunder. On May 22, 2018, Summit LLC entered into Amendment No. 3 to the Amended and Restated Credit Agreement, which further reduced the applicable margin in respect of the $633.8 million outstanding principal amount of term loans thereunder.Contents

The Company hasWe have occasionally entered into interest rate derivatives on $200.0 million of itsour term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. Themovements, however, we have not done so recently. Our last derivative expired in September 2019.
65
At our cement plants, we sponsored two non‑contributory defined benefit pension plans for certain hourly and salaried employees and two healthcare and life insurance benefits plans for certain eligible retired employees. As of January 2014, the two pension plans had been frozen to new participants and future benefit accruals and the healthcare and life insurance benefit plan has been amended to eliminate all future retiree health and life coverage for current employees. As a result of the acquisition of a cement and quarry in Davenport, Iowa and cement distribution terminals along the Mississippi River in 2015, the hourly defined benefit pension plan was amended to permit a new group of participants into the plan to accrue benefits in accordance with the terms of the collective bargaining agreement covering such Davenport employees. As a result of the collective bargaining unit negotiations in 2017, the hourly defined benefit pension plan was amended to stop future benefit accruals for the Davenport employees effective December 31, 2017. In 2015, the company adopted one new retiree healthcare plan to provide benefits prior to Medicare eligibility for certain hourly Davenport employees. As a result of the collective bargaining unit negotiations in 2017, hourly Davenport employees hired on or after January 1, 2018 are no longer eligible for retiree medical benefits. Our results of operations are affected by our net periodic benefit cost from these plans, which was $0.2 million in 2019. Assumptions that affect this expense include the discount rate and, for the pension plans only, the expected long‑term rate of return on assets. Therefore, we have interest rate risk associated with these factors.
The healthcare and life insurance benefit plans are exposed to changes in the cost of healthcare services. A one percentage‑point increase or decrease in assumed health care cost trend rates would have affected the accumulated postretirement benefit obligation by approximately $0.8 million or $(0.7) million, respectively, at December 28, 2019.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, and the results of its operations and its cash flows for each of the fiscal years in the three-year period ended December 28, 2019, December 29, 2018 and December 30, 2017,31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 28, 2019,31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 5, 202016, 2023 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Change in Accounting Principle
As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for leases as of December 30, 2018 due to the adoption of Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 842, Leases.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

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

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidatedfinancial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidatedfinancial statements;statements and (2) involved our especially challenging, subjective, or complex judgment.judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidatedfinancial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Assessing revenueRevenue recognized over time on open paving and related serviceservices contracts
As discussed in NoteNotes 1 and Note 4 to the consolidated financial statements, the Company earns revenue from providing paving and related services, which are recognized over time as performance obligations are satisfied. The Company recognizes paving and related services revenue as services are rendered based on the proportion of costs incurred to date relative to total estimated costs at completion.to complete. For the year ended December 28, 2019,31, 2022, the Company had recognized paving and related service revenue related to service revenuepaving and related services of $306$289 million.

We selected a sample of in-progress paving and related serviceservices costs incurred and compared the amountamounts and dates incurred to underlying supporting documentation. We analyzed prior year end in-progress contracts that were completed in the current year to evaluate the Company’s ability to accurately estimate paving and service related services contract forecasted costs to complete. For certain contracts, selected for testing, we evaluated the competence, capabilities, and objectivity of the project managers who determined the forecasted costs to complete for the contracts. For these contracts, we also evaluated the estimated costs at completionto complete by performing project manager interviews to obtain an understanding of the facts and circumstances of each selected contract, including changes in scope to the contract, additional estimated costs to complete, and expected completion date. For certain contracts, we also confirmed with the Company’s customers that the original contract amount, terms of the contract, modifications and billings to the customer were accurate.

SUMMIT MATERIALS, INC. AND SUBSIDIARIES
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(Dollars in tables in thousands, unless otherwise noted)

(1) Summary of Organization and Significant Accounting Policies
 
Summit Materials, Inc. (“Summit Inc.” and, together with its subsidiaries, “Summit,” “we,” “us,” “our” or the “Company”) is a vertically-integrated construction materials company. The Company is engaged in the production and sale of aggregates, cement, ready-mix concrete, asphalt paving mix and concrete products and owns and operates quarries, sand and gravel pits, 2two cement plants, cement distribution terminals, ready-mix concrete plants, asphalt plants and landfill sites. It is also engaged in paving and related services. The Company’s 3three operating and reporting segments are the West, East and Cement segments.
 
Substantially all of the Company’s construction materials, products and services are produced, consumed and performed outdoors, primarily in the spring, summer and fall. Seasonal changes and other weather-related conditions can affect the production and sales volumes of its products and delivery of services. Therefore, the financial results for any interim period are typically not indicative of the results expected for the full year. Furthermore, the Company’s sales and earnings are sensitive to national, regional and local economic conditions, weather conditions and to cyclical changes in construction spending, among other factors.
 
On September 23, 2014, Summit Inc. was formed as a Delaware corporation to be a holding company. Its sole material asset is a controlling equity interest in Summit Materials Holdings L.P. (“Summit Holdings”). Pursuant to a reorganization into a holding company structure (the “Reorganization”) consummated in connection with Summit Inc.’s March 2015 initial public offering ("IPO"), Summit Inc. became a holding corporation operating and controlling all of the business and affairs of Summit Holdings and its subsidiaries. Summit Inc. owns the majority of the partnership interests of Summit Holdings (see note 11, Stockholders’ Equity).  Summit Materials, LLC (“Summit LLC”) an indirect wholly owned subsidiary of Summit Holdings, conducts the majority of our operations. Continental Cement Company, L.L.C. (“Continental Cement”) is also a wholly owned subsidiary of Summit LLC. Summit Materials Finance Corp. (“Summit Finance”), an indirect wholly owned subsidiary of Summit LLC, has jointly issued our Senior Notes as described below.
 
Principles of Consolidation—The consolidated financial statements include the accounts of Summit Inc. and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As a result of the Reorganization, Summit Holdings became a variable interest entity over which Summit Inc. has 100% voting power and control and for which Summit Inc. has the obligation to absorb losses and the right to receive benefits.
 
The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The year ended January 2, 2021 was a 53-week year last occurred in 2015, and will occur in 2020.year.
 
For a summary of the changes in Summit Inc.’s ownership of Summit Holdings, see Note 11, Stockholders’ Equity.
 
The Company attributes consolidated stockholders’ equity and net income separately to the controlling and noncontrolling interests. The Company accountsaccounted for investments in entities for which it has an ownership of 20% to 50% using the equity method of accounting.
 
Use of Estimates—Preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, valuation of deferred tax assets, goodwill, intangibles and other long-lived assets, the tax receivable agreement (“TRA”) liability, pension and other postretirement obligations, and asset retirement obligations. Estimates also include revenue earned on contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based on historical experience and other factors, including the current economic environment. As future events and their effects cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated financial statements when the change in estimate occurs.

Table of Contents

Business and Credit Concentrations—The Company’s operations are conducted primarily across 2322 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Utah, Kansas and Missouri. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers and management does not believe that a significant concentration of credit exists with respect to any individual customer or group of customers. No single customer accounted for more than 10% of the Company’s total revenue in 2019, 20182022, 2021 or 2017.2020.
 
Accounts Receivable—Accounts receivable are stated at the amount management expects to collect from outstanding balances. Management provides for probable uncollectible amounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the collectability of individual accounts. In establishing the allowance, management considers historical losses adjusted to take into account current market conditions and its customers’ financial condition, the amount of receivables in dispute, the current receivables aging and current payment terms. Balances that remain outstanding after reasonable collection efforts are exercised are written off through a charge to the valuation allowance.
 
The balances billed but not paid by customers, pursuant to retainage provisions included in contracts, are generally due upon completion of the contracts.
 
Revenue Recognition—We earn revenue from the sale of products, which primarily include aggregates, cement, ready-mix concrete and asphalt, but also include concrete products and plastics components, and from the provision of services, which are primarily paving and related services, but also include landfill operations, the receipt and disposal of waste that is converted to fuel for use in our cement plants.

Products 

We earn revenue from the sale of products, which primarily include aggregates, cement, ready-mix concrete and asphalt, but also include concrete products, net of discounts or allowances, if any, and freight and delivery charges billed to customers. Freight and delivery charges associated with cement sales are recorded on a net basis together with freight costs within cost of sales. Revenue for product sales is recognized when evidence of an arrangement exists and when control passes,the performance obligation is satisfied, which generally is when the product is shipped. 

Aggregates and cement products are sold point-of-sale through purchase orders. When the product is sold on account, collectability typically occurs 30 to 60 days after the sale.  Revenue is recognized when cash is received from the customer at the point of sale or when the products are delivered or collected on site. There are no other timing implications that will create a contract asset or liability, and contract modifications are unlikely given the timing and nature of the transaction. Material sales are likely to have multiple performance obligations if the product is sold with delivery. In these instances, delivery most often occurs on the same day as the control of the product transfers to the customer. As a result, even in the case of multiple performance obligations, the performance obligations are satisfied concurrently and revenue is recognized simultaneously. 

Services
Services

We earn revenue from the provision of services, which are primarily paving and related services, but also include landfill operations and the receipt and disposal of waste that is converted to fuel for use in our cement plants. Revenue from the receipt of waste fuels is recognized when the waste is accepted and a corresponding liability is recognized for the costs to process the waste into fuel for the manufacturing of cement or to ship the waste offsite for disposal in accordance with applicable regulations.

Collectability of service contracts is due reasonably after certain milestones in the contract are performed. Milestones vary by project, but are typically calculated using monthly progress based on thea percentage of completion or a customer’s engineer review of progress. The majority of the time, collection occurs within 90 days of billing and cash is received within the same fiscal year as services performed. On most projects, the customer will withhold a portion of the invoice for retainage, which may last longer than a year depending on the job. 

Revenue derived from paving and related services is recognized usingover time based on the percentageproportion of costs incurred to date relative to the total estimated costs at completion, method, which approximates progress towards completion. Under the percentage of completionthis method, we recognize paving and related services revenue as services are rendered. The majority of our construction service contracts are completed within one year, but may occasionally extend beyond this time frame. The majority of our construction service contracts, and therefore, revenue, are opened and completed within one year, with the most activity during the spring, summer and fall. We estimate profit as the difference between total estimated revenue and total estimated cost of a contract and recognize that profit over the life of the

Table of Contents
term paving and related services contracts based on the proportion of costs incurred to date relative to total estimated costs at completion. We include revisions of estimated profitsrevenue on contracts in earnings under the cumulative catch-up method, under which the effect of revisions in estimates is recognized immediately. If a revised estimate of contract profitability reveals an anticipated loss on the contract, we recognize the loss in the period it is identified. 

The percentage of completionactual cost to total estimated cost method of accounting involves the use of various estimating techniques to project costs at completion, and in some cases includes estimates of recoveries asserted against the customer for changes in specifications or other disputes. Contract estimates involve various assumptions and projections relative to the outcome of future events over multiple periods, including future labor productivity and availability, the nature and complexity of the work to be performed, the cost and availability of materials, the effect of delayed performance, and the availability and timing of funding from the customer. These estimates are based on our best judgment. A significant change in one or more of these estimates could affect the profitability of one or more of our contracts. We review our contract estimates regularly to assess revisions in contract values and estimated costs at completion. Inherent uncertainties in estimating costs make it at least reasonably possible that the estimates used will change within the near term and over the life of the contracts. No material adjustments to a contract were recognized in the year ended December 28, 2019.31, 2022.

We recognize claims when the amount of the claim can be estimated reliably and its realizationit is probable.legally enforceable. In evaluating these criteria, we consider the contractual basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim.

When the contract includes variable consideration, we estimate the amount of consideration to which we will be entitled in exchange for transferring the promised goods or services to a customer. The amount of estimated variable consideration included in the transaction price is the amount for which it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Types of variable consideration include, but are not limited to, liquidated damages and other performance penalties and production and placement bonuses. 

The majority of contract modifications relate to the original contract and are often an extension of the original performance obligation. Predominately, modifications are not distinct from the terms in the original contract; therefore, they are considered part of a single performance obligation. We account for the modification using a cumulative catch-up adjustment. However, there are instances where goods or services in a modification are distinct from those transferred prior to the modification. In these situations, we account for the modifications as either a separate contract or prospectively depending on the facts and circumstances of the modification. 

Generally, construction contracts contain mobilization costs which are categorized as costs to fulfill a contract. These costs are excluded from any measure of progress toward contract fulfillment. These costs do not result in the transfer of control of a good or service to the customer and are amortized over the life of the contract. 

Costs and estimated earnings in excess of billings are composed principally of revenue recognized on contracts on a method similar to the percentage of completion method for which billings had not been presented to customers because the amounts were not billable under the contract terms at the balance sheet date. In accordance with the contract terms, the unbilled receivables at the balance sheet date are expected to be billed in following periods. Billings in excess of costs and estimated earnings represent billings in excess of revenue recognized. Contract assets and liabilities are netted on a contract-by-contract basis.

Inventories—Inventories consist of stone that has been removed from quarries and processed for future sale, cement, raw materials and finished concrete blocks. Inventories are valued at the lower of cost or marketnet realizable value and are accounted for on a first-in first-out basis or an average cost basis. If items become obsolete or otherwise unusable or if quantities exceed what is projected to be sold within a reasonable period of time, they will be charged to costs of productionrevenue in the period that the items are designated as obsolete or excess inventory. Stripping costs are costs of removing overburden and waste material to access aggregate materials and are expensed as incurred.
 
Property, Plant and Equipment, net—Property, plant and equipment are recorded at cost, less accumulated depreciation, depletion and amortization. Expenditures for additions and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Repair and maintenance costs that do not substantially expand productive capacity or extend the life of property, plant and equipment are expensed as incurred.
 
Landfill airspace is included in property, plant and equipment at cost and is amortized based on the portion of the airspace used during the period compared to the gross estimated value of available airspace, which is updated periodically as

circumstances dictate. Management reassesses the landfill airspace capacity with any changes in value recorded in cost of

Table of Contents
revenue. Capitalized landfill costs include expenditures for the acquisition of land and related airspace, engineering and permitting costs, cell construction costs and direct site improvement costs.
 
Upon disposal of an asset, the cost and related accumulated depreciation are removed from the Company’s accounts and any gain or loss is included in general and administrative expenses.
 
The Company reviews the carrying value of property, plant and equipment for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. Such indicators may include, among others, deterioration in general economic conditions, adverse changes in the markets in which an entity operates, increases in input costs that have a negative effect on earnings and cash flows or a trend of negative or declining cash flows over multiple periods.
 
Property, plant and equipment is tested for impairment at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets. As a result, the property, plant and equipment impairment test is at a significantly lower level than the level at which goodwill is tested for impairment. In markets where the Company does not produce downstream products, such as ready-mix concrete, asphalt paving mix and paving and related services, the lowest level of largely independent identifiable cash flows is at the individual aggregates operation or a group of aggregates operations collectively serving a local market or the cement operations. Conversely, in vertically-integrated markets, the cash flows of the downstream and upstream businesses are not largely independently identifiable and the vertically-integrated operations are considered the lowest level of largely independent identifiable cash flows.

Aggregates mineral bearing land and interests are included in property, plant and equipment. When leased mineral interests are acquired during a business combination, they are valued using an excess earnings approach for the life of the proven and probable reserves. Depletion expense is recorded using a units of production methodology.
 
Accrued Mining and Landfill Reclamation—The mining reclamation reserve and financial commitments for landfill closure and post-closure activities are based on management’s estimate of future cost requirements to reclaim property at both currently operating and closed sites. Estimates of these obligations have been developed based on management’s interpretation of current requirements and proposed regulatory changes and are intended to approximate fair value. Costs are estimated in current dollars, inflated until the expected time of payment, and then discounted back to present value using a credit-adjusted risk-free rate on obligations of similar maturity, adjusted to reflect the Company’s credit rating. Changes in the credit-adjusted risk-free rate do not change recorded liabilities. However, subsequent increases in the recognized obligations are measured using a current credit-adjusted risk-free rate. Decreases in the recognized obligations are measured at the initial credit-adjusted risk-free rate.
 
Significant changes in inflation rates, or the amount or, timing of future cost estimates typically result in both (1) a current adjustment to the recorded liability (and corresponding adjustment to the asset) and (2) a change in accretion of the liability and depreciation of the asset to be recorded prospectively over the remaining capacity of the unmined quarry or landfill.
 
Goodwill—Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets acquired. Goodwill recorded in connection with the Company’s acquisitions is primarily attributable to the expected profitability, assembled workforces of the acquired businesses and the synergies expected to arise after the Company’s acquisition of those businesses. Goodwill is not amortized, but is tested annually for impairment as of the first day of the fourth quarter and at any time that events or circumstances indicate that goodwill may be impaired. A qualitative approach may first be applied to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its carrying amount. If, as a result of the qualitative assessment, it is determined that an impairment is more likely than not, the two-step quantitative impairment testa Step-1 approach is then performed otherwise further analysis is not required. The two-step impairment test first identifies potential goodwill impairment forto quantitatively compare each reporting unit and then, if necessary, measures the amountunit’s fair value to its carrying value. The Step-1 analysis fails when a reporting unit's carrying value is in excess of theits fair value, resulting in an impairment loss.
 
Income Taxes—Summit Inc. is a corporation subject to income taxes in the United States. Certain subsidiaries, including Summit Holdings, or subsidiary groups of the Company are taxable separate from Summit Inc. The provision for income taxes, or Summit Inc.’s proportional share of the provision, are included in the Company’s consolidated financial statements.
 
The Company’s deferred income tax assets and liabilities are computed for differences between the tax basis and financial statement amounts that will result in taxable or deductible amounts in the future. The computed deferred balances are based on enacted tax laws and applicable rates for the periods in which the differences are expected to affect taxable income. A valuation allowance is recognized for deferred tax assets if it is more likely than not that some portion or all of the net deferred

Table of Contents
tax assets will not be realized. In making such a determination, all available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies,
Table of Contents

and results of recent operations. If the Company determines it would be able to realize its deferred tax assets for which a valuation allowance had been recorded then an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.
 
The Company evaluates the tax positions taken on income tax returns that remain open and positions expected to be taken on the current year tax returns to identify uncertain tax positions. Unrecognized tax benefits on uncertain tax positions are recorded on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50 percent likely to be realized is recognized. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense (benefit).
 
Tax Receivable Agreement—When Class A limited partnership units of Summit Holdings (“LP Units”) are exchanged for shares of Class A common stock of Summit Inc. or Summit Inc. purchases LP Units for cash, this results in increases in Summit Inc.’s share of the tax basis of the tangible and intangible assets, which increases the tax depreciation and amortization deductions that otherwise would not have been available to Summit Inc.  These increases in tax basis and tax depreciation and amortization deductions are expected to reduce the amount of cash taxes that we would otherwise be required to pay in the future. Prior to our IPO, we entered into a TRA with the pre-IPO owners that requires us to pay the pre-IPO owners or their permitted assignees 85% of the amount of cash savings, if any, in U.S. federal, state, and local income tax that we actually realize as a result of these exchanges.  These benefits include (1) increases in the tax basis of tangible and intangible assets of Summit Holdings and certain other tax benefits related to entering into the TRA, (2) tax benefits attributable to payments under the TRA, or (3) under certain circumstances such as an early termination of the TRA, we are deemed to realize, as a result of the increases in tax basis in connection with exchanges by the pre-IPO owners described above and certain other tax benefits attributable to payments under the TRA.

As noted above, we periodically evaluate the realizability of the deferred tax assets resulting from the exchange of LP Units for Class A common stock. If the deferred tax assets are determined to be realizable, we then assess whether payment of amounts under the TRA have become probable. If so, we record a TRA liability equal to 85% of such deferred tax assets. In subsequent periods, we assess the realizability of all of our deferred tax assets subject to the TRA. Should we determine a deferred tax asset with a valuation allowance is realizable in a subsequent period, the related valuation allowance will be released and consideration of a corresponding TRA liability will be assessed. The realizability of deferred tax assets, including those subject to the TRA, is dependent upon the generation of future taxable income during the periods in which those deferred tax assets become deductible and consideration of prudent and feasible tax-planning strategies.
 
The measurement of the TRA liability is accounted for as a contingent liability. Therefore, once we determine that a payment to a pre-IPO owner has become probable and can be estimated, the estimate of payment will be accrued.
 
Earnings per Share—The Company computes basic earnings per share attributable to stockholders by dividing income attributable to Summit Inc. by the weighted-average shares of Class A common stock outstanding. Diluted earnings per share reflects the potential dilution beyond shares for basic earnings per share that could occur if securities or other contracts to issue common stock were exercised, converted into common stock, or resulted in the issuance of common stock that would have shared in the Company’s earnings. Since the Class B common stock has no economic value, those shares are not included in the weighted-average common share amount for basic or diluted earnings per share. In addition, as the shares of Class A common stock are issued by Summit Inc., the earnings and equity interests of noncontrolling interests are not included in basic earnings per share.
 
Prior Year Reclassifications—We reclassified $1.2 million of other current assets to current assets held for sale for the year ended January 1, 2022 to be consistent with the current year presentation.

New Accounting Standards —Standards— In February 2016, the Financial Accounting Standards Board FASB ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842), which requires lessees to recognize most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about the leases than current U.S. GAAP requires. The ASU and subsequent amendments issued in 2018 are effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We adopted the standard effective December 30, 2018 using the modified retrospective approach. The modified retrospective approach provides a method for recording existing leases at adoption. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. The most significant impact upon adoption was the recognition of $36.8 million of operating lease right-of-use assets and $36.8 million operating lease liabilities. The standard had no material impact on our statements of operations and cash flows.
In August 2017,2018, the FASB issued ASU No. 2017-12, Derivatives2018-15, Intangibles-Goodwill and Hedging (Topic 815)Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements toCustomer’s Accounting for Hedging Activities, allowing moreImplementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which reduces the accounting complexity of implementing a cloud computing service arrangement. The ASU aligns the capitalization of implementation costs among hosting arrangements and costs incurred to develop internal-use software. We adopted this ASU in the first quarter of 2020 and the adoption of this ASU did not have a material impact on the consolidated financial and nonfinancial hedging strategiesstatements.

In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework Changes to be eligibleThe Disclosure Requirements for hedgeDefined Benefits Plans, which

The ASU is effective for fiscal years beginning after December 15, 20182020 and interim periods within those fiscal years. The adoption of this new ASU did not have a material impact on our consolidated financial results.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, increasing the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The adoption of this new ASU did not have a material impact on our consolidated financial results.

(2) Acquisitions and Dispositions
 
The Company has completed numerous acquisitions since its formation, which have been financed through a combination of debt and equity funding.formation. The operations of each acquisition have been included in the Company’s consolidated results of operations since the respective closing dates of the acquisitions. The Company measures all assets acquired and liabilities assumed at their acquisition-date fair value. Goodwill acquired during a business combination has an indefinite life and is not amortized.

Acquisition-Related Liabilities—A number of acquisition-related liabilities have been recorded subject to terms in the relevant purchase agreements, including deferred consideration and noncompete payments. Noncompete payments have been accrued where certain former owners of newly acquired companies have entered into standard noncompete arrangements. Subject to terms and conditions stated in these noncompete agreements, payments are generally made over a five-year period. Deferred consideration is purchase price consideration paid in the future as agreed to in the purchase agreement and is not contingent on future events. Deferred consideration is generally scheduled to be paid in years ranging from 5 to 20 years in annual installments. The remaining payments due under these noncompete and deferred consideration agreements are as follows:

During 2022, as part of the Company's Elevate Summit strategy to rationalize assets, the Company sold three businesses in the East segment, resulting in total cash proceeds of $373.1 million and a net gain on disposition of business of $172.4 million.

(3) Goodwill
 
As of December 28, 2019,31, 2022, the Company had 1110 reporting units with goodwill for which the annual goodwill impairment test was completed. We perform the annual impairment test on the first day of the fourth quarter each year. In 2019,2022, we performed a two-step quantitativeStep-1 analysis on all of our reporting units. Step 1 of that analysis compares the estimated the fair value of the reporting units using an income approach (i.e., a discounted cash flow technique) and a market approach to the carrying value of the reporting unit. If the estimated fair value exceeds its carrying value, the goodwill of the reporting unit is not considered impaired. If the carrying value of the reporting unit exceeds its fair value, we proceed to the second step to measure the amount of potential impairment loss. Based on this analysis, it was determined that the reporting units’ fair values were greater than their carrying values and 0no impairment charges were recognized in 2019. The accumulated impairment charges recognized in periods prior to 2017 totaled $68.2 million.2022.
 
These estimates of a reporting unit’s fair value involve significant management estimates and assumptions, including but not limited to sales prices of similar assets, assumptions related to future profitability, cash flows, and discount rates. These estimates are based upon historical trends, management’s knowledge and experience and overall economic factors, including projections of future earnings potential. Developing discounted future cash flow estimates in applying the income approach required management to evaluate its intermediate to longer-term strategies, including, but not limited to, estimates about revenue growth, operating margins, capital requirements, inflation and working capital management. The development of appropriate rates to discount the estimated future cash flows required the selection of risk premiums, which can materially affect the present value of estimated future cash flows.

Within the West segment, as a result of management changes in 2019, we integrated our Austin operations with those of our Houston operations, resulting in 1 reporting unit for goodwill.

Buildings and improvements10 - 30years
Plant, machinery and equipment157 - 20years
Office equipment3 - 7years

As of December 28, 2019, $384.731, 2022, $363.9 million of our deferred tax assets subject to our TRA are included in the net intangible assets and the net operating loss line items above.
 
Our income tax expense (benefit) was $17.1$85.5 million, $59.7$44.4 million and $(284.0)$(12.2) million in the fiscal years ended 2019, 20182022, 2021 and 2017,2020, respectively. Our effective income tax rate in 20192021 and 20182020 was impacted by the IRS interpretative guidance of TCJA,the Tax Cuts and Jobs Act (the “TCJA”), a change in state tax rates and a reductionchange in the amount of our TRA liability. We recorded an income tax benefit in fiscal 2017, primarily related to the release of the valuation allowance as discussed below, partially offset by charge related to the decrease in the federal statutory corporate tax rate.
 
The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible, as well as consideration of tax-planning strategies we may seek to utilize net operating loss carryforwards that begin to expire in 2030. Prior to 2017, we concluded that it was not more likely than not that we would fully realize those deferred tax assets, and therefore recorded a partial valuation allowance against those deferred tax assets as of December 31, 2016. However, the amount of cumulative income increased significantly during the year ended December 30, 2017. As a result of this significant positive evidence, in the third quarter of 2017, we determined that the deferred tax assets had become more likely than not of becoming realizable and therefore released the majority of the valuation allowance. The Company updates the analysis, and adjusted the valuation allowance for interest expense carryforwards limited under the TCJA based on updated forecast models each year.

On December 22, 2017, the Tax Cuts and Jobs Act
86

Table of 2017 (“TCJA”) was enacted. Among other things, the TCJA, beginning January 1, 2018, reduced the federal statutory rate from 35% to 21% and extended bonus depreciation provisions. In addition, the TCJA prescribes the application of net operating loss carryforwards generated in 2018 and beyond will be limited, 100% asset expensing will be allowed through 2022 and begin to phase out in 2023, and the amount of interest expense we are able deduct may also be limited in future years.  As a result of the enactment of TCJA and other state effective rate changes, we reduced the carrying value of our net deferred tax assets in the fourth quarter of 2017 by $216.9 million to reflect the revised federal statutory rate and other state statutory rates which will be in effect at the time those deferred tax assets are expected to be realized. The TCJA contains many provisions which continue to be clarified through new regulations. As permitted by Staff Accounting Bulletin 118 issued by the SEC on December 22, 2017, we completed our accounting of the impacts of the TCJA. Contents
We completed our analysis within 2018 consistent with the guidance of SAB 118 and any adjustments during the measurement period have been included in net earnings from continuing operations as an adjustment to income tax expense. As such, in the fourth quarter of 2018, we recorded additional tax expense of $17.6 million resulting from the IRS interpretative guidance of TCJA.

A reconciliation of the beginning and ending amount ofhad no unrecognized tax benefits is as follows:

At December 28, 201931, 2022 and December 29, 2018, there was $41.5 million and $22.7 million, respectively, of unrecognized tax benefits that if recognized would affect the annual effective tax rate.January 1, 2022, respectively. We did not recognize interest or penalties related to this amount as it is offset by other attributes. There were no uncertain tax positions for the year ended December 30, 2017.
 
Our net operating loss carryforward deferred tax assets begin to expire in 2030 and are expected to reverse before expiration. Therefore, we have not given consideration to any potential tax planning strategies as a source of future taxable income to monetize those net operating loss carryforwards. The Company will continue to monitor facts and circumstances, including our analysis of other sources of taxable income, in the reassessment of the likelihood that the tax benefit of our deferred tax assets will be realized.
     
As of December 28, 2019,31, 2022, Summit Inc. had federal net operating loss carryforwards of $822$813 million, a portion of which expire between 2030 and 2038. As of December 29, 2018, $41131, 2022, $660 million of our federal net operating losses were under the terms of our TRA. In addition, Summit Inc. has alternative minimum tax credits of $0.2 million as of December 28, 2019, which do not expire. As of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, Summit Inc. had a valuation allowance on net deferred tax assets of $1.7$1.1 million and $19.4$1.7 million, respectively, where realization of our interest tax attributes and net operating losses are not more likely than not.

Tax Receivable Agreement— During 2015, the Company entered into a TRA with the holders of LP Units and certain other pre-initial public offering owners (“Investor Entities”) that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. actually realizes (or, under certain circumstances such as an early termination of the TRA, is deemed to realize) as a result of increases in the tax basis of tangible and intangible assets of Summit Holdings and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA.
 
When LP Units are exchanged for an equal number of newly-issued shares of Summit Inc.’s Class A common stock, these exchanges result in new deferred tax assets. Using tax rates in effect as of each year end, $1.1$0.3 million and $2.0$13.7 million of deferred tax assets were created during the years ended December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively, when LP Units were exchanged for shares of Class A common stock.

Each year, we update our estimate as to when TRA payments will be made. The timing and cash tax savings of those payments can cause variations in the future value of TRA tax attributes. As noted above, when payments are made under the TRA, a portion of the payment made will be characterized as imputed interest under IRS regulations. The TCJA enacted in late 2017 contained provisions whereby interest expense deductions may be limited, and the IRS issued proposed regulations in late 2018 around the deductibility of interest expense. Under our forecast prepared at the end of 2018, we expected the amount of imputed interest based on future TRA payments would result in interest expense deductions being limited, and therefore we would not benefit from that deduction. However, based on the updated forecast model at the end of 2019, which updated our forecast of the timing of TRA payments, we believe that our interest expense deductions will not be limited under the proposed regulations. We also updated our estimate of the state income tax rate that will be in effect at the date the TRA payments are made. As a result of our updated state income tax rate, and the imputed interest limitationvariance in TRA tax attributes noted above, we have increased our TRA liability by $16.2$1.6 million and reduced itdecreased by $22.7$6.8 million as of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively.

Table of Contents

In the third quarter of 2017, as a result of the analysis of the realizability of our deferred tax assets as indicated above, we reduced the valuation allowance against our deferred tax assets, including those deferred tax assets subject to the TRA. Further, we determined the TRA liability to be probable of being payable and, as such, we recorded 85% of the deferred tax assets subject to the TRA, or $501.8 million, as TRA liability.

Our TRA liability as of December 28, 201931, 2022 and December 29, 2018January 1, 2022 was $327.0$328.4 million and $309.7$326.5 million, respectively, of which $0.0 million and $0.7 million was classified as accrued expenses, respectively.
 
Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of
Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to Summit Inc. multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate applicable to a corporate resident in New York, New York.

For the years ended December 28, 201931, 2022 and December 29, 2018,January 1, 2022, Summit Holdings paid tax distributions totaling $0.1$0.7 million and $0.1 million,zero, respectively, to holders of its LP Units, other than Summit Inc.
 
C Corporation Subsidiaries — The effective income tax rate for the C corporations differ from the statutory federal rate primarily due to (1) tax depletion expense (benefit) in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates, (3) differences between book and tax basis for divested businesses, (4) various other items such as limitations on meals and entertainment and other costs and (4)(5) unrecognized tax benefits. The effective income tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate.

Table of Contents
 
Prior to the IPO and related Reorganization, the capital structure of Summit Holdings consisted of six different classes of limited partnership units, each of which was subject to unique distribution rights. In connection with the IPO and the related Reorganization, the limited partnership agreement of Summit Holdings was amended and restated to, among other things, modify its capital structure by creating LP Units. Holders of the LP Units periodically exchange their LP Units for shares of Class A common Stock of Summit Inc.

In the first quarter of 2018, the Board of Directors vested the time-vesting units outstanding and we recognized the remaining $1.0 million of stock based compensation related to these LP units.
Omnibus Incentive Plan
 
In 2015, our Board of Directors and stockholders adopted the Summit Materials, Inc.Our 2015 Omnibus Incentive Plan (the "Plan"), which allows for grants of equity-based awards in the form of stock options, stock appreciation rights, restricted stock, and restricted stock units, performance units and other stock-based awards. The Plan authorizes the issuance of up to 13,500,00017,500,000 shares of Class A common stock in the form of restricted stock units and stock options, of which 5.67.2 million shares of Class A common stock were available for future grants as of December 28, 2019.31, 2022.

Employee Stock Purchase Plan

At the May 2021 Annual Meeting, stockholders approved the Summit Materials, Inc. 2021 Employee Stock Purchase Plan (the “ESPP”), which authorized 5,500,000 shares of Class A common stock for issuance under the ESPP. All eligible employees may voluntarily enroll to purchase the Company’s Class A common stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of six-month offering periods. Compensation expense is measured as the discount the employee is entitled to upon purchase and is recognized over the offering period. As of December 31, 2022, 5.5 million shares of Class A common stock were reserved for future issuance through the ESPP, with 5.4 million shares available for issuance.

Restricted Stock
 
Restricted Stock with Service-Based Vesting—VestingUnder the Plan, the Compensation Committee of the Board of Directors (the “Compensation Committee”) has granted restricted stock to members of the Board of Directors, executive officers and other key employees. These awards contain service conditions associated with continued employment or service. The terms of the restricted stock provide voting and regular dividend rights to holders of the awards. Upon vesting, the restrictions on the restricted stock lapse and the shares are considered issued and outstanding for accounting purposes.
 
In each of 2019, 20182022, 2021 and 2017,2020, the Compensation Committee granted restricted stock to executives and key employees under the Plan as part of our annual equity award program, which vest over a two or three year period, subject to continued employment or service.  From time to time, the Compensation Committee grants restricted stock to newly hired or promoted employees or other employees or consultants who have achieved extraordinary personal performance objectives.
 
Further, in each of 2019, 20182022, 2021 and 2017,2020, the Compensation Committee granted 65,144, 38,23230,520, 34,672 and 34,92842,736 shares, respectively, to non-employee members of the Board of Directors for their annual service as directors. These restricted stock grants vest over a one year period.
 
In measuring compensation expense associated with the grant of restricted stock, we use the fair value of the award, determined as the closing stock price for our Class A common stock on the date of grant. Compensation expense is recorded monthly over the vesting period of the award.

Restricted stock with Service-Service, Market-Condition-Based and Market-Condition-Based Vesting—Performance Based VestingIn 2019, 20182022, 2021 and 2017,2020, the Compensation Committee granted restricted stock to certain members of our executive team as part of their annual compensation package. The restricted stock vests at the end of a three year performance period, based on our total stock return (“TSR”) ranking relative to companies in the S&P Building & Construction Select Industry Index, as well as increases in our return on invested capital, subject to continued employment.
 
Compensation expense is recorded monthly over the vesting period of the awards. The following table summarizes information for the equity awards granted in 2019:2022:

The fair value of the time-vesting options granted was estimated as of the grant date using the Black-Scholes-Merton model, which requires the input of subjective assumptions, including the expected volatility and the expected term. No options to purchase common stock were granted in 2022, 2021 and 2020. The fair value of the performance stock units granted was estimated as of the grant date using Monte Carlo simulations, which requires the input of subjective assumptions, including the expected volatility and the expected term. The following table presents the weighted average assumptions used to estimate the fair value of grants in 2019, 2018 and 2017. NaN options to purchase common stock were granted in 2019 or 2018:
  Options Performance Stock Units

Risk-free interest rate1.44%0.29%0.85%
Dividend yieldN/AN/AN/A
Volatility67%70%39%
Expected term3 years3 years3 years

The risk-free rate is based on the yield at the date of grant of a U.S. Treasury security with a maturity period approximating the expected term. As Summit Holdings has not historically and does not plan to issue regular dividends, a dividend yield of zero was used. The volatility assumption is based on reported data of a peer group of publicly traded companies for which historical information was available adjusted for the Company’s capital structure. The expected term is based on expectations about future exercises and represents the period of time that the units granted are expected to be outstanding.
 
Compensation expense for time-vesting interests granted is based on the grant date fair value. The Company recognizes compensation costs on a straight-line basis over the service period, which is generally the vesting period of the award. Forfeitures are recognized as they occur. Share-based compensation expense, which is recognized in general and administrative expenses, totaled $20.4$18.3 million, $25.4$19.7 million and $49.9$28.9 million in the years ended December 28, 2019, December 29, 201831, 2022, January 1, 2022 and December 30, 2017,January 2, 2021, respectively. As of December 28, 2019,31, 2022, unrecognized compensation cost totaled $26.3$19.5 million. The weighted average remaining contractual term over which the unrecognized compensation cost is to be recognized is 1.81.7 years as of year-end 2019.2022.
 
As of December 28, 2019,31, 2022, the intrinsic value of outstanding options, restricted stock units and performance stock units was $10.7$2.4 million, $37.1$31.2 million and $9.3$11.7 million, respectively, and the remaining contractual term was 5.53.0 years, 1.00.8 years and 1.51.2 years, respectively. The weighted average strike price of 0.3 million exercisable stock options outstanding as of December 28, 201931, 2022 was $18.81$19.75 per share.

share. The intrinsic value of 2.0 million exercisable stock options as of December 28, 2019 was $10.7 million with a weighted average strike price of $18.54 and a weighted average remaining vesting period of 5.5 years.
(14) Employee Benefit Plans
 
Defined Contribution Plan—The Company sponsors employee 401(k) savings plans for its employees, including certain union employees. The plans provide for various required and discretionary Company matches of employees’ eligible compensation contributed to the plans. The expense for the defined contribution plans was $11.7$12.1 million, $11.2$10.9 million and $9.3$12.1 million for the years ended December 28, 2019, December 29, 201831, 2022, January 1, 2022 and December 30, 2017,January 2, 2021, respectively.

Defined Benefit and Other Postretirement Benefits Plans—The Company’s subsidiary, Continental Cement, sponsors 2two noncontributory defined benefit pension plans for hourly and salaried employees. The plans are closed to new participants and benefits are frozen. As a result of the collective bargaining unit negotiations in 2017, the hourly defined benefit pension plan was amended to stop future benefit accruals for the Davenport employees effective December 31, 2017. Pension benefits for eligible hourly employees are based on a monthly pension factor for each year of credited service. Pension benefits for eligible salaried employees are generally based on years of service and average eligible compensation.
Continental Cement also sponsors 2two unfunded healthcare and life insurance benefits plans for certain eligible retired employees. Effective January 1, 2014, the plan covering employees of the Hannibal, Missouri location was amended to eliminate all future retiree health and life coverage for current employees. During 2015, Continental Cement adopted 1 new unfunded healthcare plan to provide benefits prior to Medicare eligibility for certain hourly employees of the Davenport, Iowa location. As a result of the collective bargaining unit negotiations in 2017, hourly Davenport employees hired on or after January 1, 2018 are no longer eligible for retiree medical benefits.

The funded status of the pension and other postretirement benefit plans is recognized in the consolidated balance sheets as the difference between the fair value of plan assets and the benefit obligations. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (“PBO”) and for the healthcare and life insurance benefits plans, the benefit obligation is the accumulated postretirement benefit obligation (“APBO”). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. However, since the plans’ participants are not subject to future compensation increases, the plans’ PBO equals the accumulated benefit obligation (“ABO”). The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligations is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plan and use participant-specific information, such as compensation, age and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, expected return on plan assets rate of compensation increases, interest-crediting rates and mortality rates.
 
The Company uses December 31 as the measurement date for its defined benefit pension and other postretirement benefit plans.

Obligations and Funded Status—The following information is as of December 28, 201931, 2022 and December 29, 2018January 1, 2022 and for the years ended December 28, 2019, December 29, 201831, 2022, January 1, 2022 and December 30, 2017:January 2, 2021:

Plan Assets—The defined benefit pension plans’ (the “Plans”) investment strategy is to minimize investment risk while generating acceptable returns. The Plans currently invest a relatively high proportion of the plan assets in fixed income securities, while the remainder is invested in equity securities, cash reserves and precious metals. The equity securities are diversified into funds with growth and value investment strategies. The target allocation for plan assets is as follows: equity securities—30%35%; fixed income securities—63%55%; cash reserves—5%; alternatives—4%; and precious metals—2%1%. The Plans’ current investment allocations are within the tolerance of the target allocation. The Company had no Level 3 investments as of or for the years ended December 28, 201931, 2022 and December 29, 2018.January 1, 2022.
 
At year-end 20192022 and 2018,2021, the Plans’ assets were invested predominantly in fixed-income securities and publicly traded equities, but may investbe invested in other asset classes in the future subject to the parameters of the investment policy. The Plans’ investments in fixed-income assets include U.S. Treasury and U.S. agency securities and corporate bonds. The Plans’ investments in equity assets include U.S. and international securities and equity funds. The Company estimates the fair value of the Plans’ assets using various valuation techniques and, to the extent available, quoted market prices in active markets or observable market inputs. The descriptions and fair value methodologies for the Plans’ assets are as follows:
 
Fixed Income Securities—Corporate and government bonds are classified as Level 2 assets, as they are either valued at quoted market prices from observable pricing sources at the reporting date or valued based upon comparable securities with similar yields and credit ratings.

Table of Contents
 
Equity Securities—Equity securities are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.
 
Table of Contents

Cash—The carrying amounts of cash approximate fair value due to the short-term maturity.
 
Precious Metals—Precious metals are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.

The fair value of the Plans’ assets by asset class and fair value hierarchy level as of December 28, 201931, 2022 and December 29, 2018January 1, 2022 are as follows:

Multiemployer Pension Plans— In 2018, Thethrough an acquisition, the Company acquired Buildex, LLC and assumed itsan obligation to contribute to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The risks of participating in multiemployer pension plans are different from single-employer plans. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer ceases contributing to the plan, the unfunded obligations of the plan are the responsibility of the remaining participating employers.

The Company's participation in these plans for the annual period ended December 31, 2019,2022, is outlined in the table below. The ''EIN/Pension Plan Number" column provides the Employer Identification Number (EIN) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 20192022 and 20182021 is for the plan 's year end at December 31, 2018,2022, and December 31, 2017,2021, respectively. The zone status is based on information the Company received from the plan and is certified by the plan's actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded and plans in the green zone are at least 80% funded. The "FIP/RP Status Pending/Implemented" column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. The "Surcharge Imposed" column indicates

whether a surcharge has been imposed on contributions to the plan. The last column lists the expiration date(s) of the collective-bargainingcollective-

(15) Accrued Mining and Landfill Reclamation
 
The Company has asset retirement obligations arising from regulatory or contractual requirements to perform certain reclamation activities at the time that certain quarries and landfills are closed, which are primarily included in other noncurrent liabilities on the consolidated balance sheets. The current portion of the liabilities, $7.9$4.0 million and $4.1$7.4 million as of December 28, 201931, 2022 and December 29, 2018,January 1, 2022, respectively, is included in accrued expenses on the consolidated balance sheets. The total undiscounted anticipated costs for site reclamation as of December 28, 201931, 2022 and December 29, 2018January 1, 2022 were $97.4$124.9 million and $92.5$112.4 million, respectively. The liabilities were initially measured at fair value and are subsequently adjusted for accretion expense, payments and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful life. The following table presents the activity for the asset retirement obligations for the years ended December 28, 201931, 2022 and December 29, 2018:January 1, 2022:

(16) Commitments and Contingencies
 
The Company is party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded when the outcome is probable and can be reasonably estimated. 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 the Company’s consolidated financial position, results of operations or liquidity. The Company records legal fees as incurred.

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 currently not able to predict the ultimate outcome or cost of the investigation at this time.investigation.

Environmental Remediation and Site Restoration—The Company’s operations are subject to and affected by federal, state, provincial and local laws and regulations relating to the environment, health and safety and other regulatory matters. These operations require environmental operating permits, which are subject to modification, renewal and revocation. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. Despite these compliance efforts, risk of environmental liability is inherent in the operation of the Company’s business, as it is with other companies engaged in similar businesses and there can be no assurance that environmental liabilities or noncompliance will not have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity.

Other—The Company is obligated under various firm purchase commitments for certain raw materials and services that are in the ordinary course of business. Management does not expect any significant changes in the market value of these goods and services during the commitment period that would have a material adverse effect on the financial condition, results of operations and cash flows of the Company. The terms of the purchase commitments generally approximate one year.
 
(17) Leases

We lease construction and office equipment, distribution facilities and office space. Leases with an initial term of 12 months or less, including month to month leases, are not recorded on the balance sheet. Lease expense for short-term leases is recognized on a straight line basis over the lease term. For lease agreements we have entered into or reassessed, after the adoption of Topic 842, we combine lease and nonlease components. While we also own mineral leases for mining operations, those leases are outside the scope of Topic 842.ASU No. 2016-2, Leases (Topic 842). Assets acquired under finance leases are included in property, plant and equipment.

Many of our leases include options to purchase the leased equipment. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease expense were as follows:

The Company has lease agreements associated with quarry facilities under which royalty payments are made. The payments are generally based on tons sold in a particular period; however, certain agreements have minimum annual payments. Royalty expense recorded in cost of revenue during the years ended December 28, 2019, December 29, 201831, 2022, January 1, 2022 and December 30, 2017January 2, 2021 was $24.3$33.5 million, $20.1$34.8 million and $18.7$29.2 million, respectively.

(18) Fair Value of Financial Instruments
 
Fair Value Measurements—Certain acquisitions made by the Company require the payment of contingent amounts of purchase consideration. These payments are contingent on specified operating results being achieved in periods subsequent to the acquisition and will only be made if earn-out thresholds are achieved. Contingent consideration obligations are measured at fair value each reporting period. Any adjustments to fair value are recognized in earnings in the period identified.
 
The Company had entered into interest rate derivatives on $200.0 million of its term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. The interest rate derivative expired in September 2019. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The fair value of contingent consideration and derivatives as of December 28, 201931, 2022 and December 29, 2018January 1, 2022 was:

Level  1 —  UnadjustedQuoted prices in active markets for identical assets and liabilities.
Level 2 —  Observable inputs, other than quoted prices, for identicalsimilar assets or liabilities in active markets.
Level 2 —   Inputs other than Level 1 that are based on observable market data, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, inputs that are observable that are not prices and inputs that are derived from or corroborated by observable markets.
Level 3 —  Valuations developed from unobservable data, reflectingUnobservable inputs, which includes the Company’s own assumptions, which market participants would use in pricing the asset or liability.of valuation models.
  
Financial InstrumentsThe Company’s financial instruments include debt and certain acquisition-related liabilities (deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of December 31, 2022 and January 1, 2022 were:

Level 1 fair values are used to value investments in publicly-traded entities and assumed obligations for publicly-traded long-term debt.

Level 2 fair values are typically used to value acquired receivables, inventories, machinery and equipment, land, buildings, deferred income tax assets and liabilities, liabilities for asset retirement obligations, environmental remediation and compliance obligations. Additionally, Level 2 fair values are typically used to value assumed contracts at other-than-market rates.

Level 3 fair values are used to value acquired mineral reserves and leased mineral interests and other identifiable intangible assets. The fair values of mineral reserves and leased mineral interests are determined using an excess earnings approach, which requires management to estimate future cash flows. The estimate of future cash flows is based on available historical information and forecasts determined by management, but is inherently uncertain. Key assumptions in estimating future cash flows include sales price, volumes and expected profit margins, net of capital requirements. The present value of the projected net cash flows represents the fair value assigned to mineral reserves and mineral interests. The discount rate is a significant assumption used in the valuation model and is based on the required rate of return that a hypothetical market participant would assume if purchasing the acquired business.

The Level 3 fair values of contingent consideration waswere based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and a 10.0%9.5% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges are based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material adjustments to the fair value of contingent consideration in 20192022 or 2018, or to cash flow hedges in 2019 or 2018.

The fair value of debt was determined based on observable, or Level 2 inputs, such as interest rates, bond yields and quoted prices in inactive markets.2021. The fair values of the deferred consideration and noncompete obligations were determined based on unobservable, or Level 3, inputs, including the cash payment terms in the purchase agreements and a discount rate reflecting the Company’s credit risk. The discount rate used is generally consistent with that used when the obligations were initially recorded.
 
Securities with a maturity of three months or less are considered cash equivalents and the fair value of these assets approximates their carrying value.

(19) Segment Information
 
The Company has 3three operating segments: West; East;West, East and Cement, which are its reporting segments. These segments are consistent with the Company’s management reporting structure. The operating results of each segment are regularly reviewed and evaluated by the Chief Executive Officer, the Company’s Chief Operating Decision Maker (“CODM”). The CODM primarily evaluates the performance of its segments and allocates resources to them based on a segment profit metric that we call Adjusted EBITDA, which is computed as earnings from continuing operations before interest, taxes, depreciation, depletion, amortization, accretion, share-based compensation, and transaction costs, as well as various other non-recurring, non-cash amounts.
 
The West and East segments have several acquired subsidiaries that are engaged in various activities including quarry mining, aggregate production and contracting. The Cement segment is engaged in the production of Portland cement. Assets employed by each segment include assets directly identified with those operations. Corporate assets consist primarily of cash, property, plant and equipment for corporate operations and other assets not directly identifiable with a reportable business segment. The accounting policies applicable to each segment are consistent with those used in the consolidated financial statements.

Management’s Report on Internal Control Over Financial Reporting
 
The Stockholders of Summit Materials, Inc.:
 
The management of Summit Materials, Inc. and Summit Materials, LLC is responsible for establishing and maintaining adequate internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
Our management evaluated the effectiveness of our internal control over financial reporting as of December 28, 2019.31, 2022. In making this evaluation, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Based on our evaluation we believe that, as of December 28, 201931, 2022 our internal control over financial reporting is effective based on those criteria.
 
KPMG LLP has issued an audit report on the effectiveness of Summit Materials, Inc.’s internal control over financial reporting. The KPMG LLP report immediately follows this report. This annual report does not include an attestation report of Summit Materials, LLC’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by Summit Materials, LLC’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission applicable to “non-accelerated filers.”

Basis for Opinion

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

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

Definition and Limitations of Internal Control Over Financial Reporting

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

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