EXPLANATORY NOTE

This quarterly report on Form 10-Q (this “report”) is a combined quarterly report being filed separately by two registrants: Summit Materials, Inc. and Summit Materials, LLC. Each registrant hereto is filing on its own behalf all of the information contained in this report that relates to such registrant. Each registrant hereto is not filing any information that does not relate to such registrant, and therefore makes no representation as to any such information. We believe that combining the quarterly reports on Form 10-Q of Summit Materials, Inc. and Summit Materials, LLC into this single report eliminates duplicative and potentially confusing disclosure and provides a more streamlined presentation since a substantial amount of the disclosure applies to both registrants.

Unless stated otherwise or the context requires otherwise, references to “Summit Inc.” mean Summit Materials, Inc., a Delaware corporation, and references to “Summit LLC” mean Summit Materials, LLC, a Delaware limited liability company. The references to Summit Inc. and Summit LLC are used in cases where it is important to distinguish between them. We use the terms “we,” “our,” “us” or “the Company” to refer to Summit Inc. and Summit LLC together with their respective subsidiaries, unless otherwise noted or the context otherwise requires.

Summit Inc. was formed on September 23, 2014 to be a holding company. As of September 29, 2018, its sole material asset was a 97.0% economic interest in Summit Materials Holdings L.P., a Delaware limited partnership (“Summit Holdings”). Summit Inc. has 100% of the voting rights of Summit Holdings, which is the indirect parent of Summit LLC. Summit LLC is a co-issuer of our outstanding 8 ¹/₂ % senior notes due 2022 (“2022 Notes”), our 6 ¹/₈% senior notes due 2023 (“2023 Notes”) and our 5 ¹/₈% senior notes due 2025 (“2025 Notes” and collectively with the 2022 Notes and 2023 Notes, the “Senior Notes”). Summit Inc.’s only revenue for the three and nine months ended September 29, 2018 was that generated by Summit LLC and its consolidated subsidiaries. Summit Inc. controls all of the business and affairs of Summit Holdings and, in turn, Summit LLC.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report includes “forward-looking statements” within the meaning of the federal securities laws, which involve risks and uncertainties. Forward-looking statements include all statements that do not relate solely to historical or current facts, and you can identify forward-looking statements because they contain words such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “intends,” “trends,” “plans,” “estimates,” “projects” or “anticipates” or similar expressions that concern our strategy, plans, expectations or intentions. All statements made relating to our estimated and projected earnings, margins, costs, expenditures, cash flows, growth rates and financial results are forward-looking statements. These forward-looking statements are subject to risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements. We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions. While we believe that our assumptions are reasonable, it is very difficult to predict the effect of known factors, and, of course, it is impossible to anticipate all factors that could affect our actual results. In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that the results or conditions described in such statements or our objectives and plans will be realized. Important factors could affect our results and could cause results to differ materially from those expressed in our forward-looking statements, including but not limited to the factors discussed in the section entitled “Risk Factors” in Summit Inc.’s Annual Report on Form 10-K for the fiscal year ended December 30, 2017 (the “Annual Report”) and Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2018 (the “Q1 2018 10-Q”), each as filed with the Securities and Exchange Commission (the “SEC”), any factors discussed in the section entitled “Risk Factors” of this report and the following:


•	our dependence on the construction industry and the strength of the local economies in which we operate;


•	the cyclical nature of our business;


•	risks related to weather and seasonality;


•	risks associated with our capital-intensive business;


•	competition within our local markets;


•	our ability to execute on our acquisition strategy, successfully integrate acquisitions with our existing operations and retain key employees of acquired businesses;


•	our dependence on securing and permitting aggregate reserves in strategically located areas;


•	declines in public infrastructure construction and delays or reductions in governmental funding, including the funding by transportation authorities and other state agencies;


•	environmental, health, safety and climate change laws or governmental requirements or policies concerning zoning and land use;


•	conditions in the credit markets;


•	our ability to accurately estimate the overall risks, requirements or costs when we bid on or negotiate contracts that are ultimately awarded to us;


•	material costs and losses as a result of claims that our products do not meet regulatory requirements or contractual specifications;


•	cancellation of a significant number of contracts or our disqualification from bidding for new contracts;


•	special hazards related to our operations that may cause personal injury or property damage not covered by insurance;


•	our substantial current level of indebtedness;


•	our dependence on senior management and other key personnel;


•	supply constraints or significant price fluctuations in the petroleum-based resources that we use, including electricity, diesel and liquid asphalt;


•	unexpected operational difficulties;


•	interruptions in our information technology systems and infrastructure;


•	potential labor disputes; and


•	rising prices for commodities, labor and other production and delivery costs as a result of inflation or otherwise.

All subsequent written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by these cautionary statements.

Any forward-looking statement that we make herein speaks only as of the date of this report. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as required by law.

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.

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 December 30, 2017. 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 September 29, 2018, the results of operations for the three and nine months ended September 29, 2018 and September 30, 2017 and cash flows for the nine months ended September 29, 2018 and September 30, 2017.

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 into a holding company structure (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.

For a summary of the changes in Summit Inc.’s ownership of Summit Holdings, see Note 9, Stockholders’ Equity.

The Company attributes consolidated stockholders’ equity and net income separately to the controlling and noncontrolling interests. The Company accounts for investments in entities for which it has an ownership of 20% to 50% using the equity method of accounting. In October 2017, the Company acquired the 20% of Ohio Valley Asphalt, LLC held by noncontrolling interests, making it a wholly owned subsidiary.

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

Table of Contents

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.

Business and Credit Concentrations—The Company’s operations are conducted primarily across 23 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 those states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been extended 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 and nine months ended September 29, 2018 and September 30, 2017.

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 and underground storage space rental.

Products

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

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

Services

We earn revenue 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, and underground storage space rental. 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 the 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 using the percentage of completion method, which approximates progress towards completion. Under the percentage of completion 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. We estimate profit as the difference between total estimated

Table of Contents

revenue and total estimated cost of a contract and recognize that profit over the life of the contract based on input measures. We generally measure progress toward completion on long-term paving and related services contracts based on the proportion of costs incurred to date relative to total estimated costs at completion. We include revisions of estimated profits on contracts in earnings under the cumulative catch-up method, under which the effect of revisions in estimates is recognized immediately. If a revised estimate of contract profitability reveals an anticipated loss on the contract, we recognize the loss in the period it is identified.

The percentage of completion method of accounting involves the use of various estimating techniques to project costs at completion, and in some cases includes estimates of recoveries asserted against the customer for changes in specifications or other disputes. Contract estimates involve various assumptions and projections relative to the outcome of future events over multiple periods, including future labor productivity and availability, the nature and complexity of the work to be performed, the cost and availability of materials, the effect of delayed performance, and the availability and timing of funding from the customer. These estimates are based on our best judgment. A significant change in one or more of these estimates could affect the profitability of one or more of our contracts. We review our contract estimates regularly to assess revisions in contract values and estimated costs at completion. Inherent uncertainties in estimating costs make it at least reasonably possible that the estimates used will change within the near term and over the life of the contracts. No material adjustments to a contract were recognized in the three and nine months ended September 29, 2018.

We recognize claims when the amount of the claim can be estimated reliably and its realization is probable. 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 the percentage of completion method for which billings had not been presented to customers because the amounts were not billable under the contract terms at the balance sheet date. In accordance with the contract terms, the unbilled receivables at the balance sheet date are expected to be billed in following periods. Billings in excess of costs and estimated earnings represent billings in excess of revenue recognized. Contract assets and liabilities are netted on a contract-by-contract basis.

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.

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

Table of Contents

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 initial public offering (“IPO”), we entered into a TRA with the pre-IPO owners that requires us to pay the pre-IPO owners 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.

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, and the remaining 15% as an increase to additional paid-in capital. If a deferred tax asset subject to the TRA is determined not to be realizable and therefore subject to a valuation allowance, we do not record a TRA liability for 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 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.

Reclassification —Within the operating activities section on the consolidated statement of cash flows for the nine month period ended September 30, 2017, the Company reclassified $4.8 million from deferred income tax benefit, $17,000 from other current assets and $498.8 million from deferred tax assets, net, to change in deferred tax asset, net, to conform to the current year presentation.

New Accounting Standards — In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which prescribes a five-step model for revenue recognition that replaced most existing revenue recognition guidance in U.S. GAAP. The ASU supersedes nearly all existing revenue recognition guidance under U.S. GAAP and provides that an entity recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB postponed the effective date of the new revenue standard by one year to the first quarter of 2018. We adopted this ASU in the first quarter of 2018 using the modified retrospective approach, which did not have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business, which narrows the definition of a business. This ASU provides a screen to determine whether a group of assets constitutes a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated as acquisitions. If the screen is not met, this ASU (1) requires that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create an output and (2) removes the evaluation of whether a market participant could replace missing elements. Although outputs are not required for a set to be a business, outputs generally are a key element of a business; therefore, the FASB has developed more stringent criteria for sets without outputs. We adopted this ASU in the first quarter of 2018 and the adoption of this ASU did not have a material impact on the consolidated financial statements.


2.	ACQUISITIONS AND DISPOSITIONS

Since its formation, the Company has completed numerous acquisitions, which have been financed through a combination of debt and equity funding. 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. The following table summarizes the Company’s acquisitions by region and period:

(1)In addition, the Company acquired certain assets of a small ready-mix concrete operation in the second quarter of 2018.

The purchase price allocation, primarily the valuation of property, plant and equipment for the 2018 acquisitions, as well as the 2017 acquisitions that occurred after September 30, 2017, has not yet been finalized due to the recent timing of the acquisitions and status of the valuation of property, plant and equipment. The following table summarizes aggregated information regarding the fair values of the assets acquired and liabilities assumed as of the respective acquisition dates:

(1)	Reflects goodwill from 2018 acquisitions and working capital adjustments from prior year acquisitions.

The Company’s intangible assets are primarily composed of goodwill, lease agreements and reserve rights. The assets related to 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. The following table shows intangible assets by type and in total:

3.	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.

Revenue by product for the three and nine months ended September 29, 2018 and September 30, 2017 is as follows:

Senior Notes—On June 1, 2017, Summit LLC and Summit Finance (together, the “Issuers”) issued $300.0 million of 5.125% senior notes due June 1, 2025 (the “2025 Notes”). The 2025 Notes were issued at 100.0% of their par value with proceeds of $295.4 million, net of related fees and expenses. The 2025 Notes were issued under an indenture dated June 1, 2017 (as amended and supplemented, the “2017 Indenture”). The 2017 Indenture contains covenants limiting, among other things, Summit LLC and its restricted subsidiaries’ ability to incur additional indebtedness or issue certain preferred shares, pay dividends, redeem stock or make other distributions, make certain investments, sell or transfer certain assets, create liens, consolidate, merge, sell or otherwise dispose of all or substantially all of its assets, enter into certain transactions with affiliates, and designate subsidiaries as unrestricted subsidiaries. The 2017 Indenture also contains customary events of default. Interest on the 2025 Notes is payable semi-annually on June 1 and December 1 of each year commencing on December 1, 2017.

In 2016, the Issuers issued $250.0 million of 8.500% senior notes due April 15, 2022 (the “2022 Notes”). The 2022 Notes were issued at 100.0% of their par value with proceeds of $246.3 million, net of related fees and expenses. The 2022 Notes were issued under an indenture dated March 8, 2016, the terms of which are generally consistent with the 2017 Indenture. Interest on the 2022 Notes is payable semi-annually in arrears on April 15 and October 15 of each year.

In 2015, the Issuers issued $650.0 million of 6.125% senior notes due July 2023 (the “2023 Notes” and collectively with the 2022 Notes and the 2025 Notes, the “Senior Notes”). Of the aggregate $650.0 million of 2023 Notes, $350.0 million were issued at par and $300.0 million were issued at 99.375% of par. The 2023 Notes were issued under an indenture dated

July 8, 2015, the terms of which are generally consistent with the 2017 Indenture. Interest on the 2023 Notes is payable semi-annually in arrears on January 15 and July 15 of each year.

As of September 29, 2018 and December 30, 2017, the Company was in compliance with all financial covenants under the applicable indentures.

Senior Secured Credit Facilities— Summit LLC has credit facilities that provide for term loans in an aggregate amount of $650.0 million and revolving credit commitments in an aggregate amount of $235.0 million (the “Senior Secured Credit Facilities”). Under the Senior Secured Credit Facilities, required principal repayments of 0.25% of the refinanced aggregate amount of term debt are due on the last business day of each March, June, September and December commencing with the March 2018 payment. The unpaid principal balance is due in full on the maturity date, which is November 21, 2024.

On January 19, 2017, Summit LLC entered into Amendment No. 1 (“Amendment No. 1”) to the credit agreement governing the Senior Secured Credit Facilities (the “Credit Agreement”), which, among other things, reduced the applicable margin in respect of the then outstanding $640.3 million principal amount of term loans thereunder. All other material terms and provisions remain substantially identical to the terms and provisions in place immediately prior to the effectiveness of Amendment No. 1. On November 21, 2017, Summit LLC entered into Amendment No. 2 to the Credit Agreement, which, among other things, extended the maturity date from 2022 to 2024 and reduced the applicable margin in respect of the $635.4 million outstanding principal amount of term loans thereunder. On May 22, 2018, Summit LLC entered into Amendment No. 3 to the Credit Agreement, which, among other things, reduced the applicable margin in respect of the $633.8 million outstanding principal amount of term loans thereunder.

The revolving credit facility bears interest per annum equal to, at Summit LLC’s option, either (i) a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of Bank of America, N.A. and (c) LIBOR plus 1.00%, plus an applicable margin of 2.25% for base rate loans or (ii) a LIBOR rate determined by reference to Reuters prior to the interest period relevant to such borrowing adjusted for certain additional costs plus an applicable margin of 3.00% for LIBOR rate loans.

There were no outstanding borrowings under the revolving credit facility as of September 29, 2018 and December 30, 2017, leaving remaining borrowing capacity of $219.6 million as of September 29, 2018, which is net of $15.4 million of outstanding letters of credit. The outstanding letters of credit are renewed annually and support required bonding on construction projects and the Company’s insurance liabilities.

Summit LLC’s Consolidated First Lien Net Leverage Ratio, as such term is defined in the Credit Agreement, should be no greater than 4.75:1.0 as of each quarter-end. As of September 29, 2018 and December 30, 2017, Summit LLC was in compliance with all financial covenants.

Summit LLC’s wholly-owned domestic subsidiary companies, subject to certain exclusions and exceptions, are named as subsidiary guarantors of the Senior Notes and the Senior Secured Credit Facilities. In addition, Summit LLC has pledged substantially all of its assets as collateral, subject to certain exclusions and exceptions, for the Senior Secured Credit Facilities.

Other—On January 15, 2015, the Company’s wholly-owned subsidiary in British Columbia, Canada entered into an agreement with HSBC for a (i) $6.0 million Canadian dollar (“CAD”) revolving credit commitment to be used for operating activities that bears interest per annum equal to the bank’s prime rate plus 0.20%, (ii) $0.5 million CAD revolving credit commitment to be used for capital equipment that bears interest per annum at the bank’s prime rate plus 0.90% and (iii) $0.4 million CAD revolving credit commitment to provide guarantees on behalf of that subsidiary. There were no amounts outstanding under this agreement as of September 29, 2018 or December 30, 2017.


7.	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 expense (benefit) was $20.8 million and $(498.3) million in the three months ended September 29, 2018 and September 30, 2017, and our income tax expense (benefit) was $16.2 million and $(497.1) million in the nine months ended September 29, 2018 and September 30, 2017, respectively. We recorded an income tax benefit in the three months ended September 30, 2017 primarily related to the release of the valuation allowance as discussed below, partially offset by an increase in the deferred tax liability of approximately$29.6 million. Our effective income tax rate in the third quarter of 2017 is not meaningful given the release of the valuation allowance against our deferred tax assets. For the three and nine months ended September 29, 2018, the effective tax rate for Summit Inc. differs from the federal rate primarily due to (1) state taxes, (2) tax depletion expense in excess of the expense recorded under U.S. GAAP, (3) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (4) various other items such as limitations on meals and entertainment, certain stock compensation and other costs. For the three and nine months ended September 30, 2017, the effective tax rate for Summit Inc. differs from the federal rate primarily due to (1) the change in valuation allowance, (2) tax depletion expense in excess of the expense recorded under U.S. GAAP, (3) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (4) various other items such as limitations on meals and entertainment, certain stock compensation and other costs.

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 any net operating loss carryforwards scheduled to expire in the near future.

In the nine months ended September 30, 2017, based on the increase in our cumulative income, and expectation of future income generation, we determined that our deferred tax assets had become more likely than not of being realized. As such, we released the majority of the valuation allowance that had previously been recorded against our deferred tax assets. Accordingly, we reduced the valuation allowance against our deferred tax assets by $532.0 million as of September 30, 2017.

Our net operating loss carryforward deferred tax assets begin to expire in 2030 and are expected to reverse before

expiration. Therefore, we have not given consideration to any potential tax planning strategies as a source of future taxable income to monetize those net operating loss carryforwards. The Company will continue to monitor facts and circumstances, including our analysis of other sources of taxable income, in the reassessment of the likelihood that the tax benefit of our deferred tax assets will be realized.

As of September 29, 2018 and December 30, 2017, 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.

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 nine months ended September 29, 2018, 254,102 LP Units were acquired by Summit Inc. in exchange for an equal number of newly-issued shares of Summit Inc.’s Class A common stock. These exchanges resulted in net new deferred tax assets of approximately $2.2 million. As we determined that the deferred tax assets created from these exchanges are realizable and payment under the TRA is considered probable, we have recorded 85% of the increase in deferred tax assets as TRA liability and the remainder as an increase in additional paid in capital. As of September 29, 2018 and December 30, 2017, we had recorded $333.2 million and $331.9 million of TRA liability of which $0.6 million was classified as accrued expenses as of December 30, 2017. As a result of the analysis of the realizability of our deferred tax assets as of September 30, 2017, we reduced the valuation allowance against our deferred tax assets, including those deferred tax assets subject to the TRA. Further, we determined the TRA liability to be probable of being payable and, as such, we recorded 85% of the deferred tax assets subject to the TRA, or $501.8 million, as TRA liability.

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 a portion of 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 the highest federal corporate tax rate plus the highest state and local tax rate in New York, New York. In the nine months ended September 29, 2018 and September 30, 2017, we made tax distribution payments of $0.1 million and $0.1 million, respectively.

As of September 29, 2018 and December 30, 2017, Summit Inc. and its subsidiaries had not recognized any liabilities for uncertain tax positions. The Company records interest and penalties as a component of the income tax provision. No material interest or penalties were recognized in income tax expense during the three and nine months ended September 29, 2018 and September 30, 2017.


8.	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.

The following table shows the calculation of basic earnings per share:

9.	STOCKHOLDERS’ EQUITY

Equity Offering—On January 10, 2017, Summit Inc. raised $237.6 million, net of underwriting discounts, through the issuance of 10,000,000 shares of Class A common stock at a public offering price of $24.05 per share. Summit Inc. used these proceeds to purchase an equal number of LP Units.

During 2017 and 2018, certain limited partners of Summit Holdings exchanged their LP Units for shares of Class A common stock of Summit Inc. The following table summarizes the changes in our ownership of Summit Holdings:



	Summit Inc. Shares (Class A)	LP Units		Total	Summit Inc. Ownership Percentage
Balance - December 30, 2017	110,350,594	3,689,620		114,040,214	96.8	%

11.	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 pending or threatened claims and litigation will not have a material effect on the Company’s consolidated results of operations, financial position or liquidity. The Company records legal fees as incurred.

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 September 29, 2018 and December 30, 2017, $24.5 million and $20.5 million, respectively, were included in other noncurrent liabilities on the consolidated balance sheets and $3.9 million and $3.9 million, respectively, were included in accrued expenses for future reclamation costs. The total undiscounted anticipated costs for site reclamation as of September 29, 2018 and December 30, 2017 were $84.0 million and $67.9 million, respectively.

Table of Contents

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.


12.	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 Company has entered into interest rate derivatives on $200.0 million of its term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. The interest rate derivative expires in September 2019. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and will be subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The fair value of contingent consideration and derivatives as of September 29, 2018 and December 30, 2017 was:



	September 29, 2018		December 30, 2017
Current portion of acquisition-related liabilities and Accrued expenses:
Contingent consideration	$	3,011	$	594
Cash flow hedges	—		488
Acquisition-related liabilities and Other noncurrent liabilities
Contingent consideration	$	3,774	$	34,301
Cash flow hedges	—		492

The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and a 10.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges is based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material valuation adjustments to contingent consideration or derivatives as of September 29, 2018 and September 30, 2017.

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 September 29, 2018 and December 30, 2017 was:



	September 29, 2018				December 30, 2017
	Fair Value		Carrying Value		Fair Value		Carrying Value
Level 2
Long-term debt(1)	$	1,837,273	$	1,828,041	$	1,893,239	$	1,832,455
Level 3
Current portion of deferred consideration and noncompete obligations(2)	11,137		11,137		13,493		13,493
Long term portion of deferred consideration and noncompete obligations(3)	25,355		25,355		23,834		23,834


(1)	$4.8 million was included in current portion of debt as of September 29, 2018 and December 30, 2017.


(2)	Included in current portion of acquisition-related liabilities on the consolidated balance sheets.

Table of Contents


(3)	Included in acquisition-related liabilities on the consolidated balance sheets.

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.


13.	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 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 September 29, 2018 and December 30, 2017 and for the three and nine months ended September 29, 2018 and September 30, 2017:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are one of the fastest growing construction materials companies in the United States. Within our markets, we offer customers a single-source provider for construction materials and related downstream products through our vertical integration. Our materials include aggregates, which we supply across the United States, and in British Columbia, Canada, and cement, which we supply to surrounding states along the Mississippi River from Minneapolis to New Orleans. In addition to supplying aggregates to customers, we use a portion of our materials internally to produce ready-mix concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our vertically-integrated business model creates opportunities to increase aggregates sales, optimize margin at each stage of production and provide customers with efficiency gains, convenience and reliability, which we believe provides us a competitive advantage in the markets we serve.

Since our inception in 2009, we have completed dozens of acquisitions, which are organized into 12 operating companies spanning dozens of metropolitan statistical areas. Our highly experienced management team, led by our President and Chief Executive Officer, Thomas Hill, who has over 35 years of industry experience, has successfully enhanced the operations of acquired companies by focusing on scale advantages, cost efficiencies and price optimization to improve profitability and cash flow.

As of September 29, 2018, we had 3.7 billion tons of proven and probable aggregates reserves serving our aggregates and cement businesses and operated over 400 sites and plants, to which we believe we have adequate road, barge and/or railroad access.

We have three operating segments: West, East and Cement, which are also our reporting segments. We operate in 23 U.S. states and British Columbia, Canada and currently have assets in 22 U.S. states and British Columbia, Canada. The map below illustrates our geographic asset footprint.

Business Trends and Conditions

The U.S. construction materials industry is composed of four primary sectors: aggregates; cement; ready-mix concrete; and asphalt paving mix. Each of these materials is widely used in most forms of construction activity. Participants in these sectors typically range from small, privately-held companies focused on a single material, product or market to multinational corporations that offer a wide array of construction materials and services. Competition is constrained in part by the distance materials can be transported efficiently, resulting in predominantly local or regional operations. Due to the lack of product differentiation, competition for all of our products is predominantly based on price and, to a lesser extent, quality of products and service. As a result, the prices we charge our customers are not likely to be materially different from the prices charged by other producers in the same markets. Accordingly, our profitability is generally dependent on the level of demand for our products in the local and regional markets and our ability to control operating costs.

Our revenue is derived from multiple end-use markets including public infrastructure construction and private residential and nonresidential construction. Public infrastructure includes spending by federal, state, provincial and local governments for roads, highways, bridges, airports and other infrastructure projects. Public infrastructure projects have historically been a relatively stable portion of state and federal budgets. Residential and nonresidential construction consists of new construction and repair and remodel markets. Any economic stagnation or decline, which could vary by local region and market, could affect our results of operations. Our sales and earnings are sensitive to national, regional and local economic

conditions and particularly to cyclical changes in construction spending, especially in the private sector. From a macroeconomic view, we see positive indicators for the construction sector, including upward trends in highway obligations, housing starts and construction employment. All of these factors should result in increased construction activity in the private sector. However, construction activity is not consistent across the United States. Certain of our markets are showing solid growth, other markets, notably Kansas, have experienced a decrease.

Transportation infrastructure projects, driven by both federal and state funding programs, represent a significant share of the U.S. construction materials market. Federal funds are allocated to the states, which are required to match a portion of the federal funds they receive. Federal highway spending uses funds predominantly from the Federal Highway Trust Fund, which derives its revenue from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state departments of transportation to plan for their long-term highway construction and maintenance needs. Funding for the existing federal transportation funding program extends through 2020. With the nation’s infrastructure aging, there is increased demand by states and municipalities for long-term federal funding to support the construction of new roads, highways and bridges in addition to the maintaining the existing infrastructure.

In addition to federal funding, state, county and local agencies provide highway construction and maintenance funding. Our four largest states by revenue, Texas, Utah, Kansas and Missouri, represented approximately 21%, 13%, 12% and 9%, respectively, of our total revenue in 2017. The following is a summary of key funding initiatives in those states:

•

According to the Texas Department of Transportation (“TXDOT”) total annual funding available for transportation infrastructure, including state and federal funding, is estimated to be approximately $13.9 billion in fiscal year 2019 (commencing September 1, 2018), increasing to $14.3 billion by fiscal year 2020. Further, the 2019 Unified Transportation Program (“UTP”) plans for $75 billion to fund transportation projects from 2019 through 2028, up from the 2018 UTP of $71 billion and more than double the previous UTP, Proposition 1 and Proposition 7 funding initiatives. The funding available in any given year is separate and distinct from lettings, or the process of providing notice, issuing proposals, receiving proposals, and awarding contracts. In October 2018, the TXDOT updated its fiscal year 2019 lettings estimate to $6.4 billion from $5.7 billion in fiscal 2018, which provides for more than 800 transportation projects, the majority of which are expected to have a total value of less than $15 million each. Longer-term, TXDOT has indicated a target of $8 billion per year in total state and local lettings.

◦

In February 2018, the federal government approved a two-year budget agreement. Included within this package was approximately $89 billion in relief funding related to a series of natural disasters, including Hurricane Harvey, which impacted our Houston market in the second half of calendar 2017. We believe that significant federal funding stemming from the $89 billion relief package is expected to result in the construction of new water and transportation infrastructure in the Houston market from 2018 to 2020. Further, an omnibus appropriation was approved in March 2018. This bill provides approximately $2.0 billion in new funding for highway, bridge and tunnel obligations at the state level. We believe that this federal funding may utilized by state departments of transportation between March 2018 and September 2021 on the condition that the states provide some degree of matching funding, as set forth in the omnibus appropriation bill.

◦

In November 2015, Texas voters approved the ballot measure known as Proposition 7, authorizing a constitutional amendment for transportation funding. The amendment dedicates a portion of the state’s general sales and use taxes and motor vehicle sales and rental taxes to the State Highway Fund for use on non-tolled projects. Beginning in September 2017 (fiscal year 2018), if general state sales and use tax revenue exceeds $28 billion in a fiscal year, the next $2.5 billion will be directed to the State Highway Fund. Additionally, beginning in September 2019 (fiscal year 2020), if state motor vehicle sales and rental tax revenue exceeds $5 billion in a fiscal year, 35% of the amount above $5 billion will be directed to the State Highway Fund. As of July 2018, TXDOT anticipated that fiscal 2018 collections for Proposition 7 would amount to a $2.5 billion contribution in fiscal year 2019, increasing to $5.0 billion by fiscal year 2020.


◦	In November 2014, Texas voters approved a ballot measure known as Proposition 1, which authorized a portion of the severance taxes on oil and natural gas to be redirected to the State Highway Fund each year. As of September 2018, TXDOT anticipated that funding from Proposition 1 for fiscal year 2019 would be $1.37 billion, up from $734 million received in fiscal year 2018.


•	Utah’s transportation investment fund has $2.3 billion programmed for 2017 through 2022. In early 2017, Utah’s governor signed into law a measure to allow the state to issue up to $1 billion in highway general obligation bonds to accelerate funding for several projects that the Utah Transportation Commission already approved.

•

Kansas has a 10‑year $8.2 billion highway bill that was passed in May 2010. Kansas’ fiscal year 2019 transportation budget is slightly above the fiscal year 2018 budget, which was below the fiscal year 2017 budget, given austerity measures put into effect under the most recent gubernatorial administration. In May 2018, a legislative task force was convened to evaluate the current system’s condition and funding of the state’s transportation system. The task force will make recommendations on the current and future transportation system needs and the structure of the highway fund with a final report due by January 2019.


•	Missouri’s Statewide Transportation Improvement Program for 2019 through 2023 states that $4.5 billion is available for awards for highway and bridge construction.

Use and consumption of our products fluctuate due to seasonality. Nearly all of the products used by us, and by our customers, in the private construction and public infrastructure industries are used outdoors. Our highway operations and production and distribution facilities are also located outdoors. Therefore, seasonal changes and other weather-related conditions, in particular extended rainy and cold weather in the spring and fall and major weather events, such as hurricanes, tornadoes, tropical storms and heavy snows, can adversely affect our business and operations through a decline in both the use of our products and demand for our services. In addition, construction materials production and shipment levels follow activity in the construction industry, which typically occurs in the spring, summer and fall. Warmer and drier weather during the second and third quarters of our fiscal year typically result in higher activity and revenue levels during those quarters.

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

Backlog

Our products are generally delivered upon receipt of orders or requests from customers, or shortly thereafter. Accordingly, the backlog associated with product sales is converted into revenue within a relatively short period of time. Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers. Therefore, a period-over-period increase or decrease of backlog does not necessarily result in an improvement or a deterioration of our business. Our backlog includes only those products and projects for which we have obtained a purchase order or a signed contract with the customer and does not include products purchased and sold or services awarded and provided within the period. Subject to applicable contract terms, substantially all contracts in our backlog may be cancelled or modified by our customers. Historically, we have not been materially adversely affected by contract cancellations or modifications.

As a vertically-integrated business, approximately 24% of aggregates sold were used internally in our ready-mix concrete and asphalt paving mixes and approximately 73% of the asphalt paving mix were laid by our paving crews during the nine months ended September 29, 2018. Our backlog as of September 29, 2018, was 12.0 million tons of aggregates, 1.0 million cubic yards of ready-mix concrete, 2.6 million tons of asphalt and $380.7 million of construction services, which includes the value of the aggregate and asphalt tons and ready-mix concrete cubic yards that are expected to be sourced internally.

Financial Highlights

The principal factors in evaluating our financial condition and operating results for the three and nine months ended September 29, 2018 as compared to September 30, 2017, are:


•	Net revenue increased $50.6 million and $152.4 million in the three and nine months ended September 29, 2018, respectively, primarily resulting from contributions from our acquisitions.

•

Our operating income decreased $5.7 million and $29.7 million in the three and nine months ended September 29, 2018, respectively, primarily due to higher labor and transportation costs included in our cost of revenue, as well as higher levels of depreciation and amortization in 2018 resulting from our acquisitions. Further, our general and administrative expenses for the nine month period ended September 29, 2018 were higher than the comparable period in 2017 primarily due to the acquisitions which occurred in the fourth quarter of 2017 as well as the first nine months of 2018, as well as increased stock-based compensation charges in 2018.


•	In January 2017, we raised $237.6 million through the issuance of 10,000,000 shares of Class A common stock at a public offering price of $24.05 per share, resulting in net proceeds of $237.0 million.

Table of Contents


•	In June 2017, we issued $300 million of 5.125% senior notes due June 1, 2025 (the “2025 Notes”), resulting in net proceeds of $295.4 million, after related fees and expenses.


•	In September 2018, the Company sold a non-core business in the West segment, resulting in cash proceeds of $21.6 million and a total gain on the disposition of the business of $12.1 million.


•	During the third quarter of 2017, we reduced the valuation allowance against our deferred tax assets by $532.0 million, resulting in the recordation of a deferred income tax benefit of $532.0 million. Further, as those deferred tax assets were subject to our TRA, we recorded TRA expense of $501.8 million in the third quarter of 2017 as well.

Acquisitions

In addition to our organic growth, we continued to grow our business through acquisitions, completing a total of 10 acquisitions in the first nine months of 2018, of which four were in the West segment and six were in the East segment.

Results of Operations

The following discussion of our results of operations is focused on the key financial measures we use to evaluate the performance of our business from both a consolidated and operating segment perspective. Operating income and margins are discussed in terms of changes in volume, pricing and mix of revenue source (i.e., type of product sales or service revenue). We focus on operating margin, which we define as operating income as a percentage of net revenue, as a key metric when assessing the performance of the business, as we believe that analyzing changes in costs in relation to changes in revenue provides more meaningful insight into the results of operations than examining costs in isolation.

Operating income (loss) reflects our profit from continuing operations after taking into consideration cost of revenue, general and administrative expenses, depreciation, depletion, amortization and accretion and transaction costs. Cost of revenue generally increases ratably with revenue, as labor, transportation costs and subcontractor costs are recorded in cost of revenue. General and administrative expenses as a percentage of revenue vary throughout the year due to the seasonality of our business. As a result of our revenue growth occurring primarily through acquisitions, general and administrative expenses and depreciation, depletion, amortization and accretion have historically increased as well. However, as organic volumes increase, we expect our general and administrative costs to decrease as a percentage of revenue. Our transaction costs fluctuate with the level acquisition activity completed each year.

The table below includes revenue and operating income (loss) by segment for the three and nine months ended September 29, 2018 and September 30, 2017.

The statement of operations above is based on the financial results of Summit Inc. and its subsidiaries. The statement of operations of Summit LLC and its subsidiaries differs from Summit Inc. in that Summit LLC has $0.2 million and $0.5 million less interest expense than Summit Inc., in the three and nine months ended September 29, 2018. The additional interest expense for Summit Inc. is associated with a deferred consideration obligation of Summit Holdings, which is excluded from Summit LLC’s consolidated interest expense.

(1)	Adjusted EBITDA is a non-GAAP measure that we find helpful in monitoring the performance of our business. See the reconciliation below of Adjusted EBITDA to net income, which is the most directly comparable GAAP measure.

Net revenue increased $50.6 million in the three months ended September 29, 2018, primarily resulting from our acquisition program. Our increase in net revenue resulted primarily from increased sales of products and materials primarily from our acquisitions as well as organic growth in our aggregates, ready-mix and asphalt lines of business, partially offset by a decline in our cement revenues. We generated organic volume growth in our aggregates, ready-mix and asphalt lines of business during the third quarter of 2018 over the prior year period, while the cement line of business had a decrease in organic volume. We had organic average sales price growth in each of our aggregates, ready-mix concrete and asphalt lines of business during the third quarter of 2018.

Net revenue increased $152.4 million in the nine months ended September 29, 2018, primarily resulting from our acquisition program, as well as organic growth in our aggregates, ready-mix concrete and asphalt operations, partially offset by a decrease in our cement revenues. Of the increase in net revenue, $28.5 million was from increased sales of materials, $112.8 million was from increased sales of products and $11.1 million was from increased service revenue. We generated organic volume growth of 0.6% in aggregates, 2.0% in our ready-mix volumes and 0.4% in asphalt organic volumes during the first nine months of 2018 over the prior year period, while our organic cement volumes decreased by 8.1%. We had organic price

Table of Contents

growth in our aggregate, cement, ready-mix concrete and asphalt lines of business of approximately 1% to 3% during the first nine months of 2018. Additional discussion about the impact of acquisitions on each segment is presented in more detail below.

In the three months ended September 29, 2018, our net revenue growth was $39.6 million and $11.0 million from acquisitions and organic revenue, respectively. Operating income decreased by $5.7 million in the third quarter of 2018 as compared to the third quarter of 2017 primarily as inflationary increases in our cost of revenue exceeded our increases in net revenue. Our depreciation, depletion, amortization and accretion increased $5.0 million primarily due to acquisitions completed in 2017 and 2018. Further, the construction industry is experiencing a shortage in skilled labor in many markets, and as a result, we are realizing wage increases in those markets. As some of our customers are also experiencing a labor shortage, they have delayed the start of their projects, which in turn decreases our net revenues. Lastly, we experienced wetter weather conditions in most of our operating geographies in 2018 as compared to 2017, which contributed to lower revenues and operating inefficiencies, which further increased cost of revenue.

In the nine months ended September 29, 2018, our net revenue growth was $128.5 million and $23.9 million from acquisitions and organic revenue, respectively. Operating income decreased by $29.7 million in the first nine months of 2018 as compared to the first nine months of 2017 primarily as a result of increases in our costs of revenue, as well as increases in our general and administrative expenses and depreciation, depletion, amortization and accretion expense resulting from our acquisition program. Our depreciation, depletion, amortization and accretion expense increased $16.9 million primarily due to acquisitions completed in 2017 and 2018.

Our operating margin percentage decreased from 19.8% to 17.3% and from 12.5% to 9.1% in the three and nine months ended September 29, 2018, respectively, due to the items noted above. Adjusted EBITDA, as defined below, decreased by $8.7 million in the nine months ended September 29, 2018, due to higher costs of revenue which were only partially offset by increases in net revenue, as well as increases in general and administrative expenses and depreciation, depletion, amortization and accretion expense. In addition, we recorded the $6.9 million reduction in a contingent liability from one of our acquisitions as other income during the nine months ended September 29, 2018.

As a vertically-integrated company, we include intercompany sales from materials to products and from products to services when assessing the operating results of our business. We refer to revenue inclusive of intercompany sales as gross revenue. These intercompany transactions are eliminated in the consolidated financial statements. Gross revenue by line of business was as follows:

Revenue from aggregates increased $24.1 million and $54.3 million in the three and nine months ended September 29, 2018, respectively, primarily due to increased volumes. Aggregate volumes were positively affected by our acquisition program and organic growth in the West segment, offset by a decrease in organic volumes in the East segment. Organic aggregate volumes increased 3.9% in the third quarter of 2018 as compared to the same period a year ago primarily due to increases in the Intermountain, western Canada and Missouri markets, offset by decreases in our Kansas, Kentucky and southeast United States markets. Organic aggregate volumes increased 0.6% in the first nine months of 2018 as compared to the same period a year ago primarily due to increases in northeast Texas and the Intermountain region, offset by decreases in our Houston, and southeast geographies. Aggregate average sales prices of $10.20 per ton slightly increased compared to the first nine months of 2017.

Revenue from cement decreased $7.0 million and $15.8 million in the three and nine ended September 29, 2018, respectively, due primarily to volume declines as weather conditions in the first nine of 2017 were better than the comparable period in 2018, as well as increased competitive conditions in 2018. During the first nine months of 2018, pricing for cement improved by 0.8% to $113.37 per ton, primarily resulting from price increases implemented in 2017 and 2018.

Revenue from ready-mix concrete increased $25.2 million and $86.1 million in the three and nine months ended September 29, 2018, respectively, primarily from the acquisitions referred to above. Ready-mix concrete pricing of $107.69 per cubic yard in 2018 increased 2.9% as compared to the first nine months of 2017.

Revenue from asphalt increased $9.3 million and $7.0 million in the three and nine months ended September 29, 2018, respectively. In the first nine months of 2018, our organic asphalt volumes increased 0.4% and our organic asphalt pricing increased 1.2%.

Other Financial Information

Tax Receivable Agreement Expense

In the third quarter of 2017, we recorded $501.8 million of tax receivable agreement ("TRA") expense. This estimate was recorded based on the realization of our deferred tax assets subject to the TRA being more likely than not of being realized. Based on a release of the valuation allowance related to the TRA deferred tax assets discussed below, we further determined payment of those benefits had become probable under our TRA.

Income Tax Benefit

Table of Contents

Our income tax expense (benefit) was $20.8 million and $(498.3) million in the three months ended September 29, 2018 and September 30, 2017, and our income tax expense (benefit) was $16.2 million and $(497.1) million in the nine months ended September 29, 2018 and September 30, 2017, respectively. We recorded an income tax benefit in the three months ended September 30, 2017 primarily related to the release of the valuation allowance as discussed below, partially offset by an increase in the deferred tax liability of approximately $29.6 million. Our effective income tax rate in the third quarter of 2017 is not meaningful given the release of the valuation allowance against our deferred tax assets. For the three and nine months ended September 29, 2018, the effective tax rate for Summit Inc. differs from the federal rate primarily due to (1) state taxes, (2) tax depletion expense in excess of the expense recorded under U.S. GAAP, (3) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (4) various other items such as limitations on meals and entertainment, certain stock compensation and other costs. For the three and nine months ended September 30, 2017, the effective tax rate for Summit Inc. differs from the federal rate primarily due to (1) the change in valuation allowance, (2) tax depletion expense in excess of the expense recorded under U.S. GAAP, (3) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (4) various other items such as limitations on meals and entertainment, certain stock compensation and other costs.

Net revenue in the West segment increased $35.5 million and $116.3 million in the three and nine months ended September 29, 2018, respectively, primarily due to incremental revenue from acquisitions in the last three months of 2017 and in 2018. Net revenue growth from acquisitions in the three and nine months ended September 29, 2018 increased $23.1 million and $83.7 million, respectively, with the balance attributable to organic operations.

The West segment’s operating income decreased $9.4 million and $19.7 million in the three and nine months ended September 29, 2018, respectively, primarily due to increased labor costs and hydrocarbon costs included in cost of revenue, increases in general and administrative expenses, as well as higher levels of depreciation and amortization from acquisitions made in 2017 and 2018. Further, wetter weather conditions in our Texas markets had a negative effect on our operational efficiencies. Adjusted EBITDA declined $2.7 million and $1.5 million in the three and nine months ended September 29, 2018, respectively. The reduction in West segment Adjusted EBITDA in the nine months ended September 29, 2018 was due to increased costs of revenue noted above, coupled with tighter construction margins in our Texas, Utah and Vancouver markets, which were only partially offset by improved organic volume of aggregates, ready-mix concrete and asphalt, combined with increased organic average sales price growth in aggregates and ready-mix concrete. The operating margin percentage in the West segment decreased in the three months ended September 29, 2018 to 14.6% from 19.6% in the three months ended

Table of Contents

September 30, 2017, due to increased labor costs, depreciation and amortization, as well as increases in general and administrative expenses resulting from acquisitions that occurred in the last three months of 2017 and in 2018. Those same factors contributed to similar declines in operating income and operating margin percentage in the respective nine month periods.

Gross revenue from aggregates in the West segment increased $10.6 million and $22.0 million in the three and nine months ended September 29, 2018, respectively, primarily due to an increase in acquisition-related volumes in last three months of 2017 and the first nine months of 2018. The increase in aggregates volumes was primarily in our Northern Texas markets. Aggregates pricing for the three and nine months ended September 29, 2018 increased 2.7% and 4.1%, respectively, when compared to the same periods of 2017.

Revenue from ready-mix concrete in the West segment increased $25.6 million and $75.7 million in the three and nine months ended September 29, 2018, respectively, due to organic growth as well as acquisition activity. For the nine months ended September 29, 2018, our acquisition and organic volume growth was 19.8% and 4.1%, respectively.

Revenue from asphalt in the West segment increased $2.2 million and $0.9 million in the three and nine months ended September 29, 2018, respectively, primarily due to increased organic and acquisition volumes offset by lower average sales prices primarily in our northeast Texas markets. Revenue for paving and related services in the West segment increased by $6.5 million and $17.8 million in the three and nine months ended September 29, 2018, respectively, due to acquisitions.

Prior to eliminations of intercompany transactions, the net effect of volume and pricing changes on gross revenue in the nine months ended September 29, 2018 was approximately $86.6 million and $12.0 million, respectively.

Our Austin operation operates a liquid asphalt terminal in the Houston area which was damaged by Hurricane Harvey in 2017. The terminal commenced limited operations in the third quarter of 2018, however some repairs are still underway. We are in the process of filing insurance claims for not only damaged property, plant and equipment, but also under our business interruption policy. In the three and nine months ended September 29, 2018, we received $0.5 million and $2.8 million, respectively, under our property and casualty claim related to damaged or destroyed equipment. Additionally, in the three months ended September 29, 2018, we received $0.5 million related to our business interruption claim.

Net revenue in the East segment increased $22.4 million and $52.0 million in the three and nine month periods ended September 29, 2018, respectively, as compared to the same periods a year ago, primarily due to acquisition growth, and to a lesser extent, organic-related pricing. Operating income increased $1.1 million and decreased $2.5 million in the three and nine months ended September 29, 2018, respectively, over the same periods a year ago. The increase in operating income for the three months ended September 29, 2018 was primarily due to acquisition growth in aggregate volumes and net revenue, offset by increases in costs of revenue and general and administrative expenses, while the decrease in the operating income for the nine months ended September 29, 2018 was due to increases in the cost of revenue as noted above, as well as the impact of additional depreciation and general and administrative expenses from the acquisitions in the last three months of 2017 and in 2018. Adjusted EBITDA increased $1.9 million and $1.0 million in the three and nine months ended September 29, 2018, respectively, due to the items noted above relating to operating income.

Operating margin percentage for the three and nine months ended September 29, 2018 decreased to 18.8% from 20.6% and decreased to 9.6% from 11.4%, respectively, from the comparable periods a year ago, as the costs of revenue increased greater than our average sales prices.

Gross revenue from aggregates in the East segment increased $13.6 million and $32.3 million in the three and nine months ended September 29, 2018, respectively, primarily due to acquisitions in 2018. Aggregate volumes in the first nine months of 2018 increased 20.1%, as a result of acquisitions, slightly offset by a decrease in organic volumes. Aggregates pricing decreased in the nine month period of 2018 due to the impact of lower prices from acquisitions as well as competition in our markets, offset slightly by a 1.1% increase in organic pricing.

Revenue from ready-mix concrete in the East segment decreased $0.5 million and increased $10.4 million in the three and nine months ended September 29, 2018, respectively. In the three months ended September 29, 2018, declines in our organic volumes were not offset by acquisition volumes, resulting in an overall 2.8% decrease in sales volumes. In the nine months ended September 29, 2018, increases in our ready-mix volumes due to acquisitions were partially offset by declines in organic volumes.

Revenue from asphalt increased in $7.1 million and $6.2 million in the three and nine months ended September 29, 2018, respectively, when compared to the comparable periods of 2017. The $10.4 million and $8.3 million increases in paving and related service revenue in the three and nine months ended September 29, 2018, respectively, were primarily due to increases in paving activity especially in our Virginia markets.

Liquidity and Capital Resources

Our primary sources of liquidity include cash on-hand, cash provided by operations, amounts available for borrowing under our senior secured credit facilities and capital-raising activities in the debt and capital markets. As of September 29, 2018, we had $64.9 million in cash and cash equivalents and $373.3 million of working capital compared to $383.6 million and $533.6 million, respectively, at December 30, 2017. Working capital is calculated as current assets less current liabilities. There were no restricted cash balances as of September 29, 2018 or December 30, 2017. Our remaining borrowing capacity on our senior secured revolving credit facility was $219.6 million as of September 29, 2018, which is net of $15.4 million of outstanding letters of credit and is fully available to us within the terms and covenant requirements of our credit agreement governing the senior secured credit facilities (the “Credit Agreement”).

Given the seasonality of our business, we typically experience significant fluctuations in working capital needs and balances throughout the year. Our working capital requirements generally increase during the first half of the year as we build up inventory and focus on repair and maintenance and other set-up costs for the upcoming season. Working capital levels then decrease as the construction season winds down and we enter the winter months, which is when we see significant inflows of cash from the collection of receivables.

Our acquisition strategy has historically required us to raise capital through equity issuances or debt financings. As of September 29, 2018 and December 30, 2017, our long-term borrowings totaled $1.8 billion, for which we incurred $25.4 million and $76.9 million of interest expense for the three and nine months ended September 29, 2018, respectively, and $25.6 million and $70.1 million for the three and nine months ended September 30, 2017, respectively. We remain in compliance with our debt covenants and, when we have made additional issuances of senior notes to fund acquisitions, we have complied with the incurrence tests in the indentures governing our senior notes. Our senior secured revolving credit facility has been adequate to fund our seasonal working capital needs and certain acquisitions. We had no outstanding borrowings on the revolving credit facility as of September 29, 2018.

We believe we have access to sufficient financial resources from our liquidity sources to fund our business and operations, including contractual obligations, capital expenditures and debt service obligations, for at least the next twelve months. Our growth strategy contemplates future acquisitions for which we believe we have sufficient access to capital.

We and our affiliates may from time to time purchase our outstanding debt through open market purchases, privately negotiated transactions or otherwise. Purchases or retirement of debt, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Indebtedness

Please refer to the notes to the consolidated interim financial statements for detailed information about our long-term debt, scheduled maturities of long-term debt and affirmative and negative covenants, including the maximum allowable consolidated first lien net leverage ratio. As of September 29, 2018, we were in compliance with all debt covenants.

At September 29, 2018 and December 30, 2017, $1.8 billion of total debt was outstanding under our respective debt agreements. Summit LLC has senior secured credit facilities that provide for term loans in an aggregate amount of $650.0 million and revolving credit commitments in an aggregate amount of $235.0 million (the “Senior Secured Credit Facilities”). Summit LLC’s domestic wholly-owned subsidiary companies are named as guarantors of the Senior Notes and the Senior Secured Credit Facilities. Certain other partially-owned subsidiaries, and the wholly-owned Canadian subsidiary, Mainland Sand & Gravel ULC, do not guarantee the Senior Notes or Senior Secured Credit Facilities. Summit LLC has pledged substantially all of its assets as collateral for the Senior Secured Credit Facilities.

On January 19, 2017, Summit LLC entered into Amendment No. 1 (“Amendment No. 1”) to the Credit Agreement, which, among other things, reduced the applicable margin in respect of the then outstanding $640.3 million principal amount of term loans thereunder. All other material terms and provisions remain substantially identical to the terms and provisions in place immediately prior to the effectiveness of Amendment No. 1. On November 21, 2017, Summit LLC entered into Amendment No. 2 to the Credit Agreement, which, among other things, extended the maturity date from 2022 to 2024 and reduced the applicable margin in respect of the $635.4 million outstanding principal amount of term loans thereunder. On May 22, 2018, Summit LLC entered into Amendment No. 3 to the Credit Agreement, which, among other things, reduced the applicable margin in respect of the $633.8 million outstanding principal amount of term loans thereunder.

On June 1, 2017, the Issuers issued the 2025 Notes, which were issued at par value, resulting in proceeds of $295.4 million, net of related fees and expenses. Interest on the 2025 Notes is payable semi-annually on June 1 and December 1 of each year commencing on December 1, 2017.

On March 8, 2016, the Issuers issued $250.0 million in aggregate principal amount of 8.500% senior notes due April 15, 2022 (the “2022 Notes”). The 2022 Notes were issued at par and interest on the 2022 Notes is payable semi-annually in arrears on April 15 and October 15 of each year commencing on October 15, 2016.

•	Additional investment in inventory of $12.8 million consistent with the seasonality of our business for which our inventory levels typically increase in the first half of the year and begin to decrease during the third quarter.

•

Billed and unbilled accounts receivable increased by $130.6 million in the first nine months of 2017 as a result of the seasonality of our business. The majority of our sales occur in the spring, summer and fall and we typically incur an increase in accounts receivable (net billed and unbilled) during the second and third quarters of each year. This amount is typically converted to cash in the fourth and first quarters.


•	Deferred tax assets increased by $498.8 million as a result of the analysis of the realizability of our deferred tax assets offset by an increase in tax receivable agreement payment payable of $503.3 million.

The timing of payments associated with accounts payable and accrued expenses of cash, which is consistent with the seasonality of our business whereby we build-up inventory levels and incur repairs and maintenance costs to ready the business for increased sales volumes in the summer and fall. These costs are typically incurred in the first half of the year and paid by year-end. In addition, we made $71.1 million of interest payments in the nine months ended September 30, 2017.

Investing activities

During the nine months ended September 29, 2018, cash used for investing activities was $352.0 million, of which $210.9 million related to the 10 acquisitions completed in the period and $183.8 million was invested in capital expenditures, which was partially offset by $18.4 million of proceeds from asset sales. Additionally, in September 2018 we received $21.6 million of proceeds from the sale of a non-core business in the West segment.

During the nine months ended September 30, 2017, cash used for investing activities was $505.5 million, of which $371.5 million related to the 14 acquisitions completed in the period and $147.5 million was invested in capital expenditures, which was partially offset by $13.3 million of proceeds from asset sales.

Financing activities

During the nine months ended September 29, 2018, cash used in financing activities was $36.8 million. We received $15.6 million of proceeds from stock option exercises and $64.5 million from proceeds from debt issuance, which was offset by $35.3 million of payments on acquisition-related liabilities and $79.0 million of payments on debt.

During the nine months ended September 30, 2017, cash provided by financing activities was $516.0 million, which was primarily composed of $237.6 million of net proceeds from the January 2017 issuance of 10,000,000 shares of Class A common stock and $295.4 million of proceeds from the 2025 Notes, net of related fees and expenses. We made $22.6 million of payments on acquisition related liabilities, and $5.9 million in payments for debt and capital issuance costs.

Cash paid for capital expenditures

We paid cash of approximately $183.8 million in capital expenditures in the nine months ended September 29, 2018 compared to $147.5 million in the nine months ended September 30, 2017.

We estimate that we will invest between $225.0 million and $235.0 million in capital expenditures in 2018, which we have funded or expect to fund through cash on hand, cash from operations, outside financing arrangements and available

borrowings under our revolving credit facility. We expect to complete a new aggregates plant in Vancouver by year end with total expenditures in 2018 of $24.0 million, of which approximately $5 million is expected to be paid in the fourth quarter of 2018. For the remainder of the year, we have acquired land reserves in Colorado and we will continue the construction of new plants in Georgia and Central Missouri and the development of a quarry in Virginia, investing over $10.0 million on these projects in the fourth quarter. The Central Missouri and Virginia projects will be complete by year end. We have completed the construction of a new cement terminal along the Mississippi River for a total investment of $6.8 million, of which $0.5 million will be paid in the fourth quarter. Additionally, we have spent approximately $12.0 million on new and upgraded asphalt plants in northeast Texas, Kansas and Utah.

Tax Receivable Agreement

When the Company purchases LP Units for cash or LP Units are exchanged for shares of Class A common stock, this results in increases in the Company’s share of the tax basis of the tangible and intangible assets of Summit Holdings. These increases in tax basis may increase, for tax purposes, depreciation and amortization deductions and therefore reduce the amount of tax that Summit Inc. would otherwise be required to pay in the future. In connection with our IPO, we entered into a TRA with the holders of the 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 these increases in tax basis and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA. The increases in tax basis as a result of an exchange of LP Units for shares of Class A common stock, as well as the amount and timing of any payments under the TRA, are difficult to accurately estimate, as they will vary depending on a number of factors, including the timing of the exchanges, the price of our Class A common stock at the time of the exchange, the extent to which the exchanges are taxable, the amount and timing of our income and the effective tax rate.

We anticipate funding payments under the TRA from cash flows from operations, available cash and available borrowings under our Senior Secured Revolving Credit Facilities. As of September 29, 2018, we had accrued $333.2 million as TRA liability in our consolidated financial statements. We do not expect significant payments on our TRA liability to occur within the next twelve months.

Based upon a $18.18 per share price of our Class A common stock, the closing price of our stock on the last trading day of the three months ended September 29, 2018, and a contractually defined discount rate of 3.11%, we estimate that if Summit Inc. were to exercise its right to terminate the TRA, the aggregate amount required to settle the TRA would be approximately $282.0 million. Estimating the amount and the timing of payments that may be made under the TRA is by its nature difficult and imprecise, insofar as the amounts payable depends on a variety of factors, including, but not limited to, the timing of future exchanges, our stock price at the date of the exchange and the timing of the generation of future taxable income. The increases in tax basis as a result of an exchange, as well as the amount and timing of any payments under the TRA, will vary depending on a variety of factors.

Commitments and contingencies

We are party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded when the outcome is probable and can be reasonably estimated. While the ultimate results of claims and litigation cannot be predicted with certainty, management expects that the ultimate resolution of all pending or threatened claims and litigation will not have a material effect on our consolidated results of operations, financial position or liquidity. We record legal fees as incurred.

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

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

Off-Balance sheet arrangements

As of September 29, 2018, we had no material off-balance sheet arrangements.

New Accounting Pronouncements Not Yet Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which reduces the accounting complexity 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. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. We are compiling a list of our contracts and are beginning to assess the impact of adopting this ASU.

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

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

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, allowing more financial and nonfinancial hedging strategies to be eligible for hedge accounting. The ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. The adoption of this ASU is not expected to have a material impact on the consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will result in lessees recognizing most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about their leases than current U.S. GAAP requires. The ASU and subsequent amendments issued in 2018, are effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We have compiled our leases and are beginning to assess the impact of adopting this ASU.

Non-GAAP Performance Measures

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

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

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

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

(1)

The reconciliation of net income (loss) to Adjusted EBITDA is based on the financial results of Summit Inc. and its subsidiaries, which was $0.2 million and $0.7 million less than Summit LLC and its subsidiaries in the three and nine months ended September 30, 2017, and $0.2 million and $0.5 million less in the three and nine months ended September 29, 2018, due to interest expense associated with a deferred consideration obligation, which is an obligation of Summit Holdings and is thus excluded from Summit LLC’s consolidated interest expense.


(2)	In the nine months ended September 29, 2018, we negotiated a $6.9 million reduction in the amount of a contingent liability from one of our acquisitions. As we had passed the period to revise the opening balance sheet for this acquisition, the adjustment was recorded as other income.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks arising from transactions that are entered into in the normal course of business. Our operations are highly dependent upon the interest rate-sensitive construction industry as well as the general economic environment. These marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs. For a discussion of quantitative and qualitative disclosures about market risk, please refer to the Annual Report from which our exposure to market risk has not materially changed.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded when the outcome is probable and can be reasonably estimated. While the ultimate results of claims and litigation cannot be predicted with certainty, management expects that the ultimate resolution of all current pending or threatened claims and litigation will not have a material effect on our results of operations, financial position or liquidity.

In March 2018, we were notified of an investigation by the Canadian Competition Bureau (the “CCB”) into pricing practices by certain asphalt paving contractors in British Columbia, including Winvan Paving, Ltd. (“Winvan”). We believe the investigation is focused on time periods prior to our April 2017 acquisition of Winvan and we are cooperating with the CCB. Although we currently do not believe this matter will have a material adverse effect on our business, financial condition or results of operations, we are not able to predict the ultimate outcome or cost of the investigation at this time.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in the section entitled “Risk Factors” in the Annual Report, as updated by the information disclosed in the section entitled “Risk Factors” in our Q1 2018 10-Q, which could materially affect the Company’s business, financial condition, operating results or liquidity or future results. The risks described in the Annual Report and the Q1 2018 10-Q are not the only risks facing the Company. Additional risks and uncertainties not currently known to the Company or that it currently deems to be immaterial also may materially adversely affect its results of operations, financial condition or liquidity. There have been no material changes to the risk factors disclosed in the Annual Report, as updated by the Q1 2018 10-Q.
