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, two 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 three 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.

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 2122 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 20212022, 20202021 or 20192020.

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. Revenue for product sales is recognized when evidence of an arrangement exists and when control passesthe 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

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 over time based on the proportion of costs incurred to date relative to the total estimated costs at completion, which approximates progress towards completion. Under this 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-

7275

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 actual 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 January 1December 31, 2022.

We recognize claims when the amount of the claim can be estimated reliably and it is 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.

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 net 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 revenue 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

7376

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, thea twoStep-step quantitative impairment test1 approach is then performed, otherwise further analysis is not required. The two-step impairment test first identifies potential goodwill impairment forperformed to quantitatively compare each reporting unit and then,’s fair value if necessary, measures the amount of theto its carrying value. The Step-1 analysis fails when a reporting unit's carrying value is in excess of its 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

Table of Contents

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, 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 $126.7 million and $119.7 million of fixed overhead expenses related1.2 million of other current assets to production activities from general and administrative expenses to cost of revenuecurrent assets held for sale for the yearsyear ended 2020 and 2019, respectively,January 1, 2022 to conform tobe consistent with the current year presentation.

New Accounting Standards—In August 2018, the FASB issued 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 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 statements.

(2) Acquisitions and Dispositions

The Company has completed numerous acquisitions since its 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. The following table summarizes the Company’s acquisitions by region and period:

West	—	—	2
East	2	3	1

The purchase price allocation, primarily the valuation of property, plant and equipment for the acquisitions completed during the year end ended 20212022 have not yet been finalized due to the recent timing of the acquisitions, status of the valuation of property, plant and equipment and finalization of related tax returns. The following table summarizes aggregated information regarding the fair values of the assets acquired and liabilities assumed as of the respective acquisition dates:

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:

(3) Goodwill

As of January 1December 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. We initially performIn 2022, we performed a qualitativeStep-1 analysis. As a result of this analysis, it was determined that it is more likely than not that the fair value of seven reporting units were greater than its carrying value. For the remaining reporting units we perform a two-step quantitative analysis. 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 losson all of our reporting units. Based on this analysis, it was determined that the reporting units’ fair values were greater than their carrying values and no impairment charges were recognized in 20212022.

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.

(4) Revenue Recognition

We derive our revenue predominantly by selling construction materials, 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 service revenue is generated primarily from the asphalt paving services that we provide, and is recognized based on the proportion of costs incurred to date relative to the total estimated costs at completion. 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.

Depreciation on property, plant and equipment, including assets subject to capital leases, is generally computed on a straight-line basis. Depletion of mineral reserves and leased mineral interests are computed based on the portion of the reserves used during the period compared to the gross estimated value of proven and probable reserves, which is updated periodically as circumstances dictate. Leasehold improvements are amortized on a straight-line basis over the lesser of the asset’s useful life or the remaining lease term. The estimated useful lives are generally as follows:



Buildings and improvements	10 - 30	years
Plant, machinery and equipment	7 - 20	years
Office equipment	3 - 7	years
Truck and auto fleet	5 - 8	years
Mobile equipment and barges	6 - 8	years
Landfill airspace and improvements	10 - 30	years

The equipment leases generally have terms of less than five years and the building lease had an original term of 30 years. Approximately $177.60 million and $2417.6 million of the future obligations associated with the finance leases are included in accrued expenses as of January 1December 31, 2022 and January 21, 20212022, respectively, and the present value of the remaining finance lease payments, $157.02 million and $3115.70 million, respectively, is included in other noncurrent liabilities on the consolidated balance sheets. Future minimum rental commitments under long-term finance leases are $187.74 million, $72.8 million, $32.24 million, $21.60 million, and $10.08 million for the years ended 2022, 2023, 2024, 2025, 2026 and 20262027, respectively.

Assets are assessed for impairment charges when identified for disposition. The net gain from asset dispositions recognized in general and administrative expenses in fiscal years 2021, 2020 and 2019 was $5.9 million, $7.6 million and $10.7 million, respectively.

Intangible Assets—The Company’s intangible assets subject to amortization are primarily composed of operating permits, mineral lease agreements and reserve rights. Operating permits relate to permitting and zoning rights acquired outside of a business combination. The assets related to mineral lease agreements reflect the submarket royalty rates paid under agreements, primarily for extracting aggregates. The values were determined as of the respective acquisition dates by a comparison of market-royalty rates. The reserve rights relate to aggregate reserves to which the Company has the rights of ownership, but does not own the reserves. The intangible assets are amortized on a straight-line basis over the lives of the leases or permits, or computed based on the portion of the reserves used during the period compared to the gross estimated value of proven and probable reserves. The following table shows intangible assets by type and in total:

The tax attributes related to the limited liability companies are passed on to Summit Holdings and then to its partners, including Summit Inc. The tax attributes associated with the C corporation and Canadian subsidiaries are fully reflected in the Company’s consolidated financial statements. For the years ended January 1December 31, 2022, January 1, 2022 and January 2, 2021 and December 28, 2019, income taxes consisted of the following:

As of January 1December 31, 2022, $365363.19 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 $44.4 million,85.5 million, $44.4 million and $(12.2) million and $17.1 million in the fiscal years ended 2021 million in the fiscal years ended 2022, 20202021 and 20192020, respectively. Our effective income tax rate in 2021 and 2020 was impacted by the IRS interpretative guidance of TCJAthe Tax Cuts and Jobs Act (the “TCJA”), a change in state tax rates and a change in the amount of our TRA liability.

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. 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.

As of December 28, 2019 we had $41.5 million of unrecognized tax benefits that if recognized would affect the annual effective tax rate. Those benefits were subsequently recognized in the year ended January 2, 2021. 86

Table of Contents

We had no unrecognized tax benefits as of January 1December 31, 2022 and January 21, 20212022, respectively. We did not recognize interest or penalties related to this amount as it is offset by other attributes.

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 January 1December 31, 2022, Summit Inc. had federal net operating loss carryforwards of $902813 million, a portion of which expire between 2030 and 2038. As of January 1December 31, 2022, $581660 million of our federal net operating losses were under the terms of our TRA. As of January 1December 31, 2022 and January 21, 20212022, Summit Inc. had a valuation allowance on net deferred tax assets of $1.71 million and $1.7 million, respectively, where realization of our 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.

Table of Contents

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, $130.73 million and $213.47 million of deferred tax assets were created during the years ended January 1December 31, 2022 and January 21, 20212022, 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. 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 variance in TRA tax attributes noted above, we have decreasedincreased our TRA liability by $1.6.8 million and increaseddecreased by $76.68 million as of January 1December 31, 2022 and January 21, 20212022, respectively.

Our TRA liability as of January 1December 31, 2022 and January 21, 20212022 was $326328.54 million and $321326.75 million, 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 January 1December 31, 2022 and January 21, 2021, Summit Holdings did not pay any tax distributions2022, Summit Holdings paid tax distributions totaling $0.7 million and 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 (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

No material interest or penalties were recognized in income tax expense during the years ended January 1December 31, 2022, January 1, 2022 or January 2, 2021 or December 28, 2019. Tax years from 2015 to 2019 remain open and subject to audit by federal, Canadian, and state tax authorities.

(10) Earnings Per Share

Basic earnings per share is computed by dividing net earnings by the weighted average common shares outstanding and diluted net earnings is computed by dividing net earnings, adjusted for changes in the earnings allocated to Summit Inc. as a result of the assumed conversion of LP Units, by the weighted-average common shares outstanding assuming dilution.

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.

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 13,500,000 shares of Class A common stock in the form of restricted stock units and stock options.

At the May 2021 Annual Meeting, stockholders approved an increase to the number of shares of the Company’s Class A common stock that may be issued under the Plan by 4,000,000 shares of Class A common stock from the 13,500,000 shares of Class A common stock which were previously authorized for issuance to a total of 17,500,00017,500,000 shares of Class A common stock in the form of restricted stock units and stock options, of which 7.92 million shares of Class A common stock were available for future grants as of January 1December 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.

Table of Contents

Compensation expense is measured as the discount the employee is entitled to upon purchase and is recognized over the offering period. As of January 1December 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—Under 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 20212022, 20202021 and 20192020, 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 who have achieved extraordinary personal performance objectives.

Further, in each of 20212022, 20202021 and 20192020, the Compensation Committee granted 34,672,30,520, 34,672 and 42,736 and 65,144 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- and, Market-Condition-Based Vesting—In 2021and Performance Based Vesting—In 2022, 20202021 and 20192020, 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 2021:

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 20212022, 20202021 and 20192020. 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.

Table of Contents


	Performance Stock Units
	2022	2021	2020
Risk-free interest rate	1.44%	0.29%	0.85%
Dividend yield	N/A	N/A	N/A
Volatility	67%	70%	39%
Expected term	3 years	3 years	3 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 zerozero 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 $1918.73 million, $2819.97 million and $2028.49 million in the years ended January 1December 31, 2022, January 1, 2022 and January 2, 2021 and December 28, 2019, respectively. As of January 1December 31, 2022, unrecognized compensation cost totaled $2119.75 million. The weighted average remaining contractual term over which the unrecognized compensation cost is to be recognized is 1.87 years as of year-end 20212022.

As of January 1December 31, 2022, the intrinsic value of outstanding options, restricted stock units and performance stock units was $62.04 million, $5931.52 million and $1611.57 million, respectively, and the remaining contractual term was 3.90 years, 0.8 years and 1.12 years, respectively. The weighted average strike price of 0.3 million exercisable stock options outstanding as of January 1December 31, 2022 was $19.75 per share.

(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 $1012.91 million, $1210.19 million and $1112.71 million for the years ended January 1December 31, 2022, January 1, 2022 and January 2, 2021 and December 28, 2019, respectively.

Table of Contents

Defined Benefit and Other Postretirement Benefits Plans—The Company’s subsidiary, Continental Cement, sponsors two noncontributory defined benefit pension plans for hourly and salaried employees. The plans are closed to new participants and benefits are frozen. 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 two unfunded healthcare and life insurance benefits plans for certain eligible retired employees.

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.

Weighted-average assumptions used to determine net periodic benefit cost for years ended January 1December 31, 2022, January 1, 2022 and January 2, 2021 and December 28, 2019:


	2022		2021		2020

Expected long-term rate of return on plan assets	5.00%	N/A	5.00%	N/A	7.00%	N/A

The expected long-term return on plan assets is based upon the Plans’ consideration of historical and forward-looking returns and the Company’s estimation of what a portfolio, with the target allocation described below, will earn over a long-term horizon. The discount rate is derived using the FTSE Above Median Pension Discount Curve.

AssumedThe assumed health care cost trend rates wererate for year end 2022 was 8.0% as of year-end 2021 and 2020, grading to an ultimate7.0% grading to 4.46% in 2042. As of year end 2021, the assumed trend rate ofwas 7.0% grading to 4.575% in 20352032. Assumed health care cost trend rates have a significant effect on the amounts reported for the Company’s healthcare and life insurance benefits plans.

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—3035%; fixed income securities—6355%; cash reserves—5%; alternatives—4%; and precious metals—21%. 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 January 1December 31, 2022 and January 21, 20212022.

At year-end 20212022 and 20202021, 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.

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 January 1December 31, 2022 and January 21, 20212022 are as follows:

Multiemployer Pension Plans— In 2018, through an acquisition, the Company assumed an 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, 20212022, 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 20212022 and 20202021 is for the plan 's year end at December 31, 20212022, and December 31, 20202021, 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-

(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, $74.40 million and $107.04 million as of January 1December 31, 2022 and January 21, 20212022, respectively, is included in accrued expenses on the consolidated balance sheets. The total undiscounted anticipated costs for site reclamation as of January 1December 31, 2022 and January 21, 20212022 were $112124.49 million and $112.84 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

(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.

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, we combine lease and nonlease components. While we also own mineral leases for mining operations, those leases are outside the scope of 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:

(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 fair value of contingent consideration as of January 1December 31, 2022 and January 21, 20212022 was:


	2022		2021
Current portion of acquisition-related liabilities and Accrued expenses:
Contingent consideration	$	336	$	129

Acquisition-related liabilities and Other noncurrent liabilities:
Contingent consideration	$	4,981	$	1,239

The fair value accounting guidance establishes the following fair value hierarchy that prioritizes the inputs used to measure fair value:

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.

Financial Instruments—The 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 January 1December 31, 2022 and January 21, 20212022 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 were based on projected probability-weighted cash payments and a 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. There were no material adjustments to the fair value of contingent consideration in 20212022 or 20202021. The fair values of the deferred consideration and noncompete obligations were determined based on 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 three operating segments: 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.

The following tables display selected financial data for the Company’s reportable business segments as of and for the years ended January 1December 31, 2022, January 1, 2022 and January 2, 2021 and December 28, 2019:

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 January 1December 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 January 1December 31, 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.”

Summit Materials, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Summit Materials, Inc. and subsidiaries' (the Company) internal control over financial reporting as of January 1December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 1December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of January 1December 31, 2022 and January 21, 20212022, the related consolidated statements of operations, comprehensive income, cash flows, and changes in stockholders’ equity for each of the fiscal years in the three-year period ended January 1December 31, 2022, and the related notes (collectively, the consolidated financial statements), and our report dated February 2416, 20222023 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit 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.
