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. Summit Inc. is a holding corporation operating and controlling all of the business and affairs of Summit Materials Holdings L.P. (“Summit Holdings”) and its subsidiaries, and through Summit Holdings conducts its business. Summit Inc. owns the majority of the partnership interests of Summit Holdings (see Note 9, Stockholders’ Equity). Summit Materials, LLC (“Summit LLC”), an indirect wholly owned subsidiary of Summit Holdings, conducts the majority of our operations. Summit Materials Finance Corp. (“Summit Finance”), an indirect wholly owned subsidiary of Summit LLC, has jointly issued our Senior Notes as described below. Basis of Presentation —These unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and the notes thereto as of and for the year ended January 1, 2022. The Company continues to follow the accounting policies set forth in those audited consolidated financial statements. Management believes that these consolidated interim financial statements include all adjustments, normal and recurring in nature, that are necessary to present fairly the financial position of the Company as of April 2, 2022, the results of operations for the three months ended April 2, 2022 and April 3, 2021 and cash flows for the three months ended April 2, 2022 and April 3, 2021. 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. For a summary of the changes in Summit Inc.’s ownership of Summit Holdings, see Note 9, Stockholders’ Equity. Use of Estimates —Preparation of these consolidated financial statements in conformity with 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, 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. Business and Credit Concentrations— The Company’s operations are conducted primarily across 21 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 the three months ended April 2, 2022 or April 3, 2021. 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 from the provision of services, which are primarily paving and related services. Products: Revenue for product sales is recognized when evidence of an arrangement exists and when control passes, which generally is when the product is shipped. Services: We earn revenue from the provision of services, which are primarily paving and related services, which are typically calculated using monthly progress based on the percentage of completion or a customer’s engineer review of progress. 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 are for work that occurs mostly during the spring, summer and fall. 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. 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. 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 Period 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.

Business Acquisition [Line Items]
ACQUISITIONS, DISPOSTIONS, GOODWILL AND INTANGIBLES	ACQUISITIONS, DISPOSITIONS, GOODWILL AND INTANGIBLES The Company has completed numerous acquisitions since its formation, which have been financed through a combination of debt and equity funding and available cash. 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. Changes in the carrying amount of goodwill, by reportable segment, from January 1, 2022 to April 2, 2022 are summarized as follows: West East Cement Total Balance—January 1, 2022 $ 570,509 $ 388,585 $ 204,656 $ 1,163,750 Dispositions (1) — (12,036) — (12,036) Foreign currency translation adjustments 621 — — 621 Goodwill allocated to assets held for sale — (6,059) — (6,059) Balance—April 2, 2022 $ 571,130 $ 370,490 $ 204,656 $ 1,146,276 _______________________________________________________________________ (1) Reflects goodwill derecognition from dispositions completed during the three months ended April 2, 2022. 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 certain 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.

INCOME TAXES	INCOME TAXES Summit Inc.’s tax provision includes its proportional share of Summit Holdings’ tax attributes. Summit Holdings’ subsidiaries are primarily limited liability companies but do include certain entities organized as C corporations and a Canadian subsidiary. 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 accounts. Our income tax benefit was $4.7 million in the three months ended April 2, 2022 and our income tax benefit was $5.4 million in the three months ended April 3, 2021. The effective tax rate for Summit Inc. differs from the federal statutory tax rate primarily due to (1) state taxes, (2) tax depletion expense in excess of the expense recorded under U.S. GAAP, (3) basis differences in assets divested, (4) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (5) various other items such as limitations on meals and entertainment, certain stock compensation and other costs. As of April 2, 2022 and January 1, 2022, Summit Inc. had a valuation allowance of $1.7 million, which relates to certain deferred tax assets in taxable entities where realization is not more likely than not. No material interest or penalties were recognized in income tax expense during the three months ended April 2, 2022 and April 3, 2021. Tax Receivable Agreement —The Company is party to a TRA with certain current and former 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. 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. In the three months ended April 2, 2022, there were no LP Units acquired by Summit Inc. in exchange for an equal number of newly-issued shares of Summit Inc.’s Class A common stock. As of April 2, 2022 and January 1, 2022, we had recorded $326.5 million and $326.5 million of TRA liability, 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.

INCOME TAXES	INCOME TAXES Summit LLC is a limited liability company and passes its tax attributes for federal and state tax purposes to its parent company and is generally not subject to federal or state income tax. However, certain subsidiary entities file federal, state and Canadian income tax returns due to their status as taxable entities in the respective jurisdiction. The effective income tax rate for the C Corporations differs from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) basis differences in assets divested, (3) state income taxes and the effect of graduated tax rates and (4) various other items, such as limitations on meals and entertainment and other costs. The effective income tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate. No material interest or penalties were recognized in income tax expense during the three months ended April 2, 2022 and April 3, 2021.

LEASES	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 Accounting Standards Update 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.

Loss Contingencies [Line Items]
COMMITMENTS AND CONTINGENCIES	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. The Company has asset retirement obligations arising from regulatory and contractual requirements to perform reclamation activities at the time certain quarries and landfills are closed. As of April 2, 2022 and January 1, 2022, $37.0 million and $37.7 million, respectively, were included in other noncurrent liabilities on the consolidated balance sheets and $4.3 million and $7.4 million, respectively, were included in accrued expenses for future reclamation costs. The total undiscounted anticipated costs for site reclamation as of April 2, 2022 and January 1, 2022 were $107.6 million and $112.4 million, respectively. 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.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
FAIR VALUE	FAIR VALUE 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 April 2, 2022 and January 1, 2022 was: April 2, 2022 January 1, 2022 Current portion of acquisition-related liabilities and Accrued expenses: Contingent consideration $ 133 $ 129 Acquisition-related liabilities and Other noncurrent liabilities: Contingent consideration $ 1,115 $ 1,239 The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including 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 valuation adjustments to contingent consideration as of April 2, 2022 and April 3, 2021. 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 April 2, 2022 and January 1, 2022 was: April 2, 2022 January 1, 2022 Fair Value Carrying Value Fair Value Carrying Value Level 1 Long-term debt(1) $ 1,596,591 $ 1,607,767 $ 1,653,085 $ 1,609,298 Level 3 Current portion of deferred consideration and noncompete obligations(2) 12,945 12,945 12,981 12,981 Long term portion of deferred consideration and noncompete obligations(3) 21,813 21,813 32,130 32,130 (1) $6.4 million was included in current portion of debt as of April 2, 2022 and January 1, 2022.

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. 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.

Segment Reporting Information [Line Items]
SEGMENT INFORMATION	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, our Company’s Chief Operating Decision Maker (“CODM”). The CODM primarily evaluates the performance of the Company’s segments and allocates resources to them based on a segment profit metric that we call Adjusted EBITDA, which is computed as earnings from operations before interest, taxes, depreciation, depletion, amortization, accretion, and share-based compensation, as well as various other non-recurring, non-cash amounts. Beginning with the first quarter of 2021, the Company no longer adjusts for transaction costs, as those costs are recurring cash payments, and are included in general and administrative expenses. The West and East segments have several 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 April 2, 2022 and January 1, 2022 and for the three months ended April 2, 2022 and April 3, 2021: Three months ended April 2, 2022 April 3, 2021 Revenue*: West $ 252,232 $ 251,133 East 122,490 136,042 Cement 46,225 40,669 Total revenue $ 420,947 $ 427,844 *Intercompany sales are immaterial and the presentation above only reflects sales to external customers.

SUMMARY OF ORGANIZATION AND S_2

SUMMARY OF ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES - (Policies)	3 Months Ended
	Apr. 02, 2022
Summary Of Significant Accounting Policies And Recent Accounting Pronouncements [Line Items]
Basis of Presentation	Basis of Presentation —These unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and the notes thereto as of and for the year ended January 1, 2022. The Company continues to follow the accounting policies set forth in those audited consolidated financial statements. Management believes that these consolidated interim financial statements include all adjustments, normal and recurring in nature, that are necessary to present fairly the financial position of the Company as of April 2, 2022, the results of operations for the three months ended April 2, 2022 and April 3, 2021 and cash flows for the three months ended April 2, 2022 and April 3, 2021.
Principles of Consolidation	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. For a summary of the changes in Summit Inc.’s ownership of Summit Holdings, see Note 9, Stockholders’ Equity.
Use of Estimates	Use of Estimates —Preparation of these consolidated financial statements in conformity with 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, 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.
Business and Credit Concentrations	Business and Credit Concentrations— The Company’s operations are conducted primarily across 21 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 the three months ended April 2, 2022 or April 3, 2021.
Revenue Recognition	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 from the provision of services, which are primarily paving and related services. Products: Revenue for product sales is recognized when evidence of an arrangement exists and when control passes, which generally is when the product is shipped. Services: We earn revenue from the provision of services, which are primarily paving and related services, which are typically calculated using monthly progress based on the percentage of completion or a customer’s engineer review of progress. 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 are for work that occurs mostly during the spring, summer and fall. 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.
Earnings per Share	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 Period Reclassifications	Prior Period 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.
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 Accounting Standards Update 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.
