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, and its consolidated subsidiaries. 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, unless otherwise noted or the context otherwise requires.

Summit Inc. was formed on September 23, 2014 to be a holding company. Its sole material asset is a 27.8% economic interest in Summit Materials Holdings L.P. (“Summit Holdings”) as of June 27, 2015. Summit Inc. has 100% of the voting rights of Summit Holdings, which is the indirect parent of Summit LLC, a co-issuer of our outstanding 10 ¹/₂% senior notes due 2020 (the “2020 Notes”). Summit Inc.’s only revenue for the three and six months ended June 27, 2015 is that generated by Summit LLC. Pursuant to a reorganization into a holding corporation structure (the “Reorganization”) consummated in connection with Summit Inc.’s initial public offering (“IPO”), Summit Inc. became a holding company operating and controlling 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 prospectus (the “Prospectus”), as filed with the Securities and Exchange Commission (the “SEC”) on March 13, 2015, 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 such acquired businesses;

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

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

• changes in 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;

• interruptions in our information technology systems and infrastructure; and

• other factors as described in the Prospectus.

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.

SUMMIT MATERIALS, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(Tables in thousands, except share amounts)

1. SUMMARY OF ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Summit Materials, Inc. (“Summit Inc.” and, together with its subsidiaries, the “Company”) is a vertically-integrated construction materials company. The Company is engaged in the production and sale of aggregates, cement, ready-mixed concrete, asphalt paving mix and concrete products and owns and operates quarries, sand and gravel pits, a cement plant, cement distribution terminals, ready-mixed concrete plants, asphalt plants and landfill sites. It is also engaged in paving and related services. The Company is organized by geographic region and has three operating segments, which are also its reporting segments: the West; Central; and East regions.

Substantially all of the Company’s 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 and to cyclical changes in construction spending, among other factors.

On September 23, 2014, Summit Inc. was formed as a Delaware corporation to be a holding company. Its sole material asset is a controlling equity interest in Summit Materials Holdings L.P. (“Summit Holdings”). Pursuant to a reorganization into a holding company structure (the “Reorganization”) consummated in connection with Summit Inc.’s initial public offering, Summit Inc. became a holding corporation operating and controlling all of the business and affairs of Summit Holdings and its subsidiaries and, through Summit Holdings, conducts its business. Certain investment funds affiliated with Blackstone Capital Partners V L.P. and Silverhawk Summit, L.P. (collectively, the “Sponsors”), as well as Summit Inc., are the primary owners of Summit Holdings.

Initial Public Offering—Summit Inc. commenced operations on March 11, 2015 upon the pricing of the initial public offering of its Class A common stock (“IPO”). Summit Inc. raised $433.0 million, net of underwriting discounts, through the issuance of 25,555,555 shares of Class A common stock at a public offering price of $18.00 per share. Summit Inc. used the offering proceeds to purchase a number of newly-issued Class A Units (“LP Units”) from Summit Holdings equal to the number of shares of Class A common stock issued to the public. Summit Inc. caused Summit Holdings to use these proceeds: (i) to redeem $288.2 million in aggregate principal amount of outstanding 10 ¹/₂% senior notes due January 31, 2020 (“2020 Notes”) at a redemption price of 100% and an applicable premium thereon; (ii) to purchase 71,428,571 Class B Units of Continental Cement Company, L.L.C. (“Continental Cement”); (iii) to pay a one-time termination fee of $13.8 million primarily to affiliates of the Sponsors in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The $288.2 million redemption of 2020 Notes was completed in the second quarter of 2015 at a redemption price equal to par plus an applicable premium of $38.2 million plus $5.2 million of accrued and unpaid interest.

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 (the “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 audited consolidated financial statements of Summit Holdings and the notes thereto as of and for the year ended December 27, 2014 included in Summit Inc.’s prospectus filed with the SEC on March 13, 2015. The Company’s financial position as of December 27, 2014, the results of operations for the three and six months ended June 28, 2014 and cash flows for the six months ended June 28, 2014 reflect those of Summit Holdings. The Company continues to follow the accounting policies set forth in those 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 June 27, 2015, the results of operations for the three and six months ended June 27, 2015 and June 28, 2014 and cash flows for the six months ended June 27, 2015 and June 28, 2014. All significant intercompany balances and transactions have been eliminated.

The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The 53-week year occurs approximately once every seven years and will occur in 2015. The additional week in the 53-week year will be included in the fourth quarter.

The consolidated financial statements of the Company include the accounts of Summit Inc. and its subsidiaries, including noncontrolling interests. As a result of the Reorganization, Summit Holdings became a variable interest entity. Summit Inc. is the primary beneficiary of Summit Holdings as a result of its 100% voting power and control over Summit Holdings and its obligation to absorb losses and its right to receive benefits of Summit Holdings and thus consolidates Summit Holdings in its consolidated financial statements with a corresponding noncontrolling interest elimination of 72.2%.

Noncontrolling interests in consolidated subsidiaries represent a 20% ownership in Ohio Valley Asphalt, LLC and, prior to the IPO and concurrent purchase of the noncontrolling interests of Continental Cement, a 30% redeemable ownership in Continental Cement.

Use of Estimates—Preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, 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. Management adjusts such estimates and assumptions when circumstances dictate. 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—As of June 27, 2015, the Company’s operations are conducted primarily across 17 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Kansas, Kentucky, Utah and Missouri. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers, and management does not believe that any significant concentrations of credit exist with respect to individual customers or groups of customers. No single customer accounted for more than 10% of the Company’s total revenue in the three and six months ended June 27, 2015 and June 28, 2014.

Earnings per Share—The Company computes basic earnings per share attributable to stockholders by dividing income attributable to Summit Inc. by the weighted-average Class A common shares 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 shares have no economic value, they are not included in the weighted-average common share amount for basic or diluted earnings per share. In addition, as the Class A common shares are issued by Summit Inc., the earnings and equity interests of noncontrolling interests are not included in basic or diluted earnings per share.

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. Contingent consideration as of June 27, 2015 and December 27, 2014 was:

	June 27,		December 27,
	2015		2014
Current portion of acquisition-related liabilities:
Current portion of contingent consideration	$	4,486	$	2,375
Acquisition-related liabilities:
Contingent consideration	$	4,193	$	5,379

The fair values are based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% 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. There were no material valuation adjustments to contingent consideration obligations in the three or six months ended June 27, 2015 or June 28, 2014.

7

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 June 27, 2015 and December 27, 2014 was:

	June 27, 2015				December 27, 2014
	Fair Value		Carrying Value		Fair Value		Carrying Value
Level 2
Long-term debt(1)	$	780,155	$	827,247	$	1,101,873	$	1,064,917
Level 3
Current portion of deferred consideration and noncompete obligations(2)		17,909		17,909		16,027		16,027
Long term portion of deferred consideration and noncompete obligations(3)		38,676		38,676		37,357		37,357

(1) $5.3 million included in current portion of debt as of June 27, 2015 and December 27, 2014. Excludes $66.0 million outstanding on the revolving credit facility as of June 27, 2015.

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

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

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.

Redeemable Noncontrolling Interest— On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit Holdings. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 of Summit Inc.’s Class A common shares and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016.

New Accounting Standards — In April 2015, the FASB issued a new accounting standard to simplify the presentation of debt issuance costs. Accounting Standards Update (“ASU”) 2015-03,Simplifying the Presentation of Debt Issuance Costs, changes the presentation of debt issuance costs in financial statements. Under the ASU, an entity will present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The guidance will be applied retrospectively to all prior periods (i.e., the balance sheet for each period will be adjusted). Had the Company adopted this guidance as of the current period, both Other Assets (noncurrent) and Long-term Debt as of June 27, 2015 and December 27, 2014, would have decreased by $11.8 million and $16.8 million, respectively.

In April 2015, the FASB issued a new accounting standard, ASU 2015-04,Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets, which gives an employer whose fiscal year-end does not coincide with a calendar month-end (e.g., an entity that has a 52- or 53-week fiscal year) the ability, as a practical expedient, to measure defined benefit retirement obligations and related plan assets as of the month-end that is closest to its fiscal year-end. The ASU is effective for public business entities for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early application is permitted, and the ASU should be applied prospectively. The Company does not expect the adoption of this ASU to have a material effect on its financial position or results of operations.

In May 2014, the FASB issued a new accounting standard to improve and converge the financial reporting requirements for revenue from contracts with customers. ASU No. 2014-09,Revenue from Contracts with Customers, prescribes a five-step model for revenue recognition that will replace most existing revenue recognition guidance in U.S. GAAP. The ASU will supersede 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,

8

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. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB decided to delay the effective date of the new revenue standard by one year, or to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements.

Reclassifications— Certain amounts in the prior year have been reclassified to conform to the presentation in the consolidated financial statements as of and for the three and six months ended June 27, 2015.

2. REORGANIZATION

Prior to the IPO and Reorganization, the capital structure of Summit Holdings consisted of six different classes of limited partnership interests (Class A-1, Class A-2, Class B-1, Class C, Class D-1 and Class D-2), each of which was subject to unique distribution rights. There were no outstanding Class A-2 interests. In connection with the IPO and the Reorganization, the limited partnership agreement of Summit Holdings was amended and restated to, among other things, modify its capital structure by creating a single new class of units (the “LP Units”), referred to as the “Reclassification.” Immediately following the Reclassification, 69,007,297 LP Units were outstanding. In addition, in substitution for part of the economic benefit of the Class C and Class D interests that was not reflected in the conversion of such interests to LP Units, warrants were issued to holders of Class C interests to purchase an aggregate of 160,333 shares of Class A common stock, and options were issued to holders of Class D interests to purchase an aggregate of 4,358,842 shares of Class A common stock (“leverage restoration options”). In each case, the exercise price of such warrants and leverage restoration options was the IPO price of $18.00 per share. In conjunction with the Reclassification of the equity-based awards, the Company recognized a $14.5 million modification charge in general and administrative costs in the three months ended March 28, 2015.

The leverage restoration options were granted under the Summit Materials, Inc. 2015 Omnibus Incentive Plan (the “Omnibus Incentive Plan”). The leverage restoration options that correlate to time-vesting interests vest over four years, beginning on the Reclassification date and the leverage restoration options that correlate to performance-vesting interests vest only when both the relevant return multiple is achieved and a four year time-vesting condition is satisfied. The time-based vesting condition for both the time-vesting and performance-vesting interests will be satisfied with respect to 25% of the performance-vesting options on each of the first four anniversaries of the Reclassification date, subject to the employee’s continued employment through the applicable vesting date. The number of leverage restoration options granted in respect of each Class D interest was based on the IPO price.

The Company also granted 240,000 options to purchase shares of Class A common stock under the Omnibus Incentive Plan to certain employees some of whom had not previously been granted equity-based interests. These stock options have an exercise price of $18.00 per share, the IPO price, and are subject to a time-based vesting condition that will be satisfied with respect to 25% of the award on each of the first four anniversaries of the grant date, subject to the employee’s continued employment through the applicable vesting date.

2020 Notes—The 2020 Notes were issued under an indenture dated January 30, 2012 (as amended and supplemented, the “Indenture”) by Summit Materials, LLC (“Summit LLC”) and Summit Materials Finance Corp. (collectively, the “Issuers”). The 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 the Company’s assets, enter into certain transactions with affiliates, and designate subsidiaries as unrestricted subsidiaries. The Indenture also contains customary events of default. As of June 27, 2015 and December 27, 2014, the Company was in compliance with all covenants. Interest on the 2020 Notes is payable semi-annually in arrears.

In April 2015, using proceeds from the IPO, $288.2 million aggregate principal amount of the outstanding 2020 Notes were redeemed at a price equal to par plus an applicable premium. As a result of the redemption, a net charge of $31.3 million was recognized, which was composed of $38.2 million for the applicable prepayment premium and $4.7 million for the write-off of deferred financing fees, which was partially offset by an $11.6 million net benefit from the write-off the original issuance premium and discount.

On September 8, 2014 and January 17, 2014, the Issuers issued an additional $115.0 million and $260.0 million, respectively, aggregate principal amount of 2020 Notes (the “Additional Notes”), receiving proceeds of $409.3 million, before payment of fees and expenses and including an aggregate $34.3 million premium. The proceeds from the sale of the Additional Notes were used for the purchases of acquisitions, to make payments on the revolving credit facility and for general corporate purposes. The Additional Notes are treated as a single series with the $250.0 million of 2020 Notes (the “Existing Notes”) and have substantially the same terms as those of the Existing Notes. The Additional Notes and the Existing Notes are treated as one class under the Indenture.

Senior Secured Credit Facilities— Summit LLC has credit facilities which provide for term loans in an aggregate amount of $422.0 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 term debt are due on the last business day of each March, June, September and December. The unpaid principal balance was due in full on the maturity date, which was January 30, 2019. In July 2015, the outstanding balance of the terms loans was refinanced, extending the maturity date to 2022. See further discussion of this refinancing in note 13, Subsequent Events.

On March 11, 2015, Summit LLC entered into Amendment No. 3 to the credit agreement governing the Senior Secured Credit Facilities, which became effective on March 17, 2015 upon the consummation of the IPO. The amendment: (i) increased the size of the revolving credit facility from $150.0 million to $235.0 million; (ii) extended the maturity date of the revolving credit facility to March 11, 2020; (iii) amended certain covenants; and (iv) permits periodic tax distributions as contemplated in a tax receivable agreement, dated as of March 11, 2015, with Summit Holdings. As a result of this amendment, $0.4 million of financing fees were charged to earnings in the six months ended June 27, 2015.

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 2.5% 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 3.5% for LIBOR rate loans. The interest rate in effect at June 27, 2015 was 3.6%.

There were $66.0 million of outstanding borrowings under the revolving credit facility as of June 27, 2015, leaving remaining borrowing capacity of $144.8 million, which is net of $24.2 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.

11

Summit LLC must adhere to certain financial covenants related to its Consolidated First Lien Net Leverage Ratio and Interest Coverage Ratio, as each such term is defined in the Senior Secured Credit Facilities. The Consolidated First Lien Net Leverage Ratio, reported each quarter, should be no greater than 4.5:1.0. The interest coverage ratio must be at least 1.85:1.0. As of June 27, 2015 and December 27, 2014, Summit LLC was in compliance with all covenants.

Summit LLC’s wholly-owned domestic subsidiary companies, subject to certain exclusions and exceptions, are named as subsidiary guarantors of the 2020 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.

Interest expense related to debt totaled $14.8 million and $36.8 million for the three and six months ended June 27, 2015, respectively, and $19.3 million and $36.5 million for the three and six months ended June 28, 2014, respectively. The following table presents the activity for the deferred financing fees for the six months ended June 27, 2015 and June 28, 2014:

There were no amounts outstanding under this agreement as of June 27, 2015.

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. 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 subsidiaries are fully reflected in the Company’s accounts.

As of June 27, 2015 and December 27, 2014, 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 for the three and six months ended June 27, 2015 and June 28, 2014.

Summit Inc.— As of the IPO, Summit Inc. had a net deferred tax asset of $50.5 million, which primarily consisted of a $69.0 million temporary difference related to the tax intangible assets basis in excess of book, offset by the $6.9 million and $10.9 million book aggregate reserves and fixed assets in excess of tax basis, respectively.

In assessing the realizability of deferred tax assets, including the deferred tax assets resulting from the expected taxable loss in 2015, management determined that it was more likely than not that the deferred tax assets will not be realized. 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 and consideration of tax-planning strategies. Considering these factors, a full valuation allowance was recorded for Summit Inc.’s net deferred tax assets as of the IPO date and June 27, 2015, which has resulted in no provision for Summit Inc.’s income taxes in the three and six months ended June 27, 2015.

C Corporation Subsidiaries—The effective income tax rate for these entities differs from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates and (3) certain non-recurring items, such as differences in the treatment of transaction costs, which are often not deductible for tax purposes.

Tax Receivable Agreement—Upon the consummation of the Reorganization, the Company entered into a tax receivable agreement with the holders of LP Units and certain other indirect pre-IPO owners (“Investor Entities”) that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result of (i) increases in tax basis of the tangible and intangible assets of Summit Holdings resulting from future exchanges of LP Units for shares of Class A common stock and (ii) the utilization of certain net operating losses of the Investor Entities and certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. As of June 27, 2015, no LP units had been exchanged.

Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to each holder of LP Units multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate applicable to an individual or corporate resident in New York, New York (or a corporate resident in certain circumstances). In the three and six months ended June 27, 2015, the Company declared distributions totaling $16.4 million, $11.8 million were paid in cash to Summit Holdings’ partners, excluding Summit Inc., and $4.6 million were paid to Summit Inc. in July 2015.

8. NET LOSS PER SHARE

Immediately prior to the consummation of the Company’s IPO, the Company did not have outstanding common stock. In conjunction with the IPO, Summit Inc. sold 25,555,555 shares of Class A shares common stock to the public and issued 1,029,183 shares of Class A common stock in conjunction with the purchase of the noncontrolling interest of Continental Cement. The outstanding stock options and warrants granted in connection with the IPO are excluded from the calculations below as they would have an antidilutive effect.

Basic and diluted earnings per share for discontinued operations attributable to Summit Inc. were $0.01 in the three and six months ended June 27, 2015.

9. 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’s policy is to record legal fees as incurred.

Litigation and Claims—The Company is obligated under an indemnification agreement entered into with the sellers of Harper Contracting, Inc., Harper Sand and Gravel, Inc., Harper Excavating, Inc., Harper Ready Mix Company, Inc. and Harper Investments, Inc. (collectively, “Harper”) for the sellers’ 40% ownership interests in a joint venture agreement. The Company has the rights to any benefits under the joint venture as well as the assumption of any obligations, but does not own equity interests in the joint venture. The joint venture incurred significant losses on a highway project in Utah, which resulted in requests for funding from the joint venture partners and, ultimately, from the Company. Through June 27, 2015, the Company has funded $8.8 million, of which $4.0 million was funded in 2012 and $4.8 million was funded in 2011. On April 2, 2015, the Utah Department of Transportation filed suit in the Fourth District Court of Utah County, Utah against the joint venture and the parties to the joint venture seeking damages of at least $29.4 million. As of June 27, 2015 and December 27, 2014, an accrual of $4.3 million was recorded in other noncurrent liabilities as management’s best estimate of loss related to this matter.

During the ordinary course of business, there may be revisions to project costs and conditions that can give rise to change orders on construction contracts. Revisions can also result in claims made against a customer or subcontractor to recover project variances that have not been satisfactorily addressed through change orders with a customer. As of June 27, 2015 and December 27, 2014, the Company had unapproved change orders and claims of $1.4 million ($1.2 million in accounts receivable and $0.2 million in costs and estimated earnings in excess of billings) and $3.9 million ($1.2 million in accounts receivable, $0.5 million in costs and estimated earnings in excess of billings and $2.2 million in other assets), respectively.

Environmental Remediation—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 position, results of operations or liquidity in the future.

14

Other— In the ordinary course of business, the Company enters into various firm purchase commitments for certain raw materials and services. The terms of the purchase commitments are generally less than one year. 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 position, results of operations or liquidity of the Company.

12. RELATED PARTY TRANSACTIONS

Under the terms of a transaction and management fee agreement between Summit Holdings and Blackstone Management Partners L.L.C. (“BMP”), whose affiliates include controlling stockholders of the Company, BMP provided monitoring, advisory and consulting services to the Company through March 17, 2015. Under the terms of the agreement, BMP was permitted to assign, and had assigned, a portion of the fees to which it is entitled to Silverhawk Summit, L.P. and to certain other equity investors.

The management fee was calculated based on the greater of $300,000 or 2.0% of the Company’s annual consolidated profit, as defined in the agreement, which are included in general and administrative expenses. The Company incurred management fees due to BMP totaling $1.0 million during the period between December 28, 2014 and March 17, 2015 and $1.3 million and $2.3 million in the three and six months ended June 28, 2014, respectively. During these periods, the Company paid immaterial amounts to Silverhawk Summit, L.P. and to other equity investors.

Also under the terms of the transaction and management fee agreement, BMP undertook financial and structural analysis, due diligence investigations, corporate strategy and other advisory services and negotiation assistance related to acquisitions for which the Company paid BMP transaction fees equal to 1.0% of the aggregate enterprise value of any acquired entity or, if such transaction was structured as an asset purchase or sale, 1.0% of the consideration paid for or received in respect of the assets acquired or disposed. The Company paid BMP $0.6 million and $2.3 million during the three and six months ended June 28, 2014, respectively. During these periods, the Company paid immaterial amounts to Silverhawk Summit, L.P. and to other equity investors. The acquisition-related fees paid pursuant to this agreement are included in transaction costs.

In connection with the IPO, the transaction and management fee agreement with BMP was terminated on March 17, 2015 for a final payment of approximately $13.8 million, $13.4 million was paid to affiliates of Blackstone and the remaining $0.4 million was paid to affiliates of Silverhawk Summit, L.P. and to certain other equity investors.

In addition to the transaction and management fees paid to BMP, the Company reimburses BMP for direct expenses incurred, which were not material in the three and six months ended June 27, 2015 and June 28, 2014.

On April 16, 2015, the Company entered into an agreement with Lafarge North America Inc. (“Lafarge”) to purchase certain assets, including a cement plant, a quarry and seven cement distribution terminals (the “Davenport Assets”) for a purchase price of $450.0 million cash and a cement distribution terminal in Bettendorf, Iowa. At closing, $370.0 million of the purchase price was due and the remaining $80.0 million is due to the seller no later than December 31, 2015. Summit Holdings entered into a commitment letter dated April 16, 2015, with Blackstone Capital Partners V L.P. (“BCP”) for equity financing up to $90.0 million in the form of a preferred equity interest (the “Equity Commitment Financing”). The proceeds of the Equity Commitment Financing would be used to pay the $80.0 million deferred purchase price associated with the Davenport acquisition if a public offering of Summit Inc.’s Class A common stock cannot be effected by December 31, 2015. Summit Holdings paid a $1.8 million commitment fee to BCP in the six months ended June 27, 2015.

Blackstone Advisory Partners L.P., an affiliate of Blackstone, served as an initial purchaser of $5.75 million and $13.0 million principal amount of the 2020 Notes issued in September 2014 and January 2014, respectively, and received compensation in connection therewith.

Cement sales to companies owned by a former noncontrolling member of Continental Cement were approximately $1.4 million during the period between December 28, 2014 and March 11, 2015 and $4.5 million and $6.2 million during the three and six months ended June 28, 2014, respectively. Accounts receivables due from the former noncontrolling member were $0.2 million as of December 27, 2014.

In the first quarter of 2014, the Company made an interest payment of $0.7 million to a certain former noncontrolling member of Continental Cement for a related party note. The principal balance on the note was repaid in 2012.

In the six months ended June 28, 2014, the Company sold certain assets associated with the production of concrete blocks, including inventory and equipment, to a related party for $2.3 million.

13. SUBSEQUENT EVENTS

On August 5, 2015, Summit Inc. priced the offering of 19,500,000 shares of its Class A common stock at a price to the public of $25.75 per share. The underwriters have been granted a 30-day option to purchase up to an additional 2,925,000 shares of Class A common stock. The offering is expected to close on August 11, 2015, subject to customary closing conditions. Summit Inc. intends to use all of the net proceeds from the offering to purchase for cash 3,750,000 newly-issued LP Units from Summit Holdings and 15,750,000 outstanding LP Units from certain pre-IPO owners, including affiliates of the Sponsors and certain of the Company’s directors and officers. Summit Holdings intends to use the proceeds it receives to pay all or a portion of the $80.0 million deferred purchase price of the Davenport Assets and for general corporate purposes.

On July 17, 2015, the Company acquired certain assets of Lafarge, including a cement plant, a quarry and seven cement distribution terminals for a purchase price of $450.0 million cash and a cement distribution terminal in Bettendorf, Iowa. Due to the recent nature of the acquisition, it is impracticable to include a schedule of the fair value of the assets acquired and liabilities assumed as of the acquisition date and the Davenport Assets’ interim results of operations for the three and six months ended June 30, 2015.

On July 8, 2015, the Issuers issued $350.0 million in aggregate principal amount of 6.125% senior notes due July 15, 2023 (the “2023 Notes”). The 2023 Notes were issued at 100% of their par value. Interest on the 2023 Notes is payable semi-annually on January 15 and July 15 of each year commencing on January 15, 2016. On July 17, 2015, Summit LLC refinanced its term loan

18

under the Senior Secured Credit Facilities (the “Refinancing”). The Refinancing, among other things: (i) reduced the applicable margins used to calculate interest rates for term loans under our Senior Secured Credit Facilities to 3.25% for LIBOR rate loans and 2.25% for base rate loans, subject to a LIBOR floor of 1.00% (and one 25 basis point step down upon Summit LLC achieving a certain first lien net leverage ratio); (ii) increased term loans borrowed under our term loan facility to an aggregate $650.0 million; and (iii) created additional flexibility under the financial maintenance covenants, which are tested quarterly, by increasing the applicable maximum Consolidated First Lien Net Leverage Ratio (as defined in the credit agreement governing the Senior Secured Credit Facilities).

The Company used the net proceeds from the 2023 Notes and the Refinancing to finance an initial $370.0 million cash purchase price for the Davenport Assets, to refinance its existing senior secured term loan facility, to redeem $183.0 million aggregate principal amount of its outstanding 2020 Notes and to pay related fees and expenses. The remaining $80.0 million of the purchase price for the Davenport Assets is due to Lafarge no later than December 31, 2015 and accrues interest at an annual rate of 7.5%, payable monthly.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our consolidated interim financial statements and the related notes and other information included in this report.

Overview

We are one of the fastest growing construction materials companies in the United States. Our materials include aggregates, which we supply across the country, with a focus on Texas, Kansas, Kentucky, Utah and Missouri, and cement, which we supply primarily in Missouri, Iowa and along the Mississippi River. Within our markets, we offer customers a single-source provider for construction materials and related downstream products through our vertical integration. In addition to supplying aggregates to customers, we use our materials internally to produce ready-mixed concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our vertical integration creates opportunities to increase aggregates volumes, optimize margin at each stage of production and provide customers with efficiency gains, convenience and reliability, which we believe gives us a competitive advantage.

We have completed 36 acquisitions, which are organized into 11 operating companies that make up our three distinct operating segments—West, Central and East regions—spanning 18 U.S. states and British Columbia, Canada and 33 metropolitan statistical areas. Our highly experienced management team, led by our President and Chief Executive Officer, Tom Hill, a 30-year industry veteran, has successfully enhanced the operations of acquired companies by focusing on scale advantages, cost efficiencies and pricing discipline to improve profitability and cash flow.

As of June 27, 2015, we had 2.1 billion tons of proven and probable aggregates reserves serving our aggregates and cement businesses and operated over 200 sites and plants, to which we believe we have adequate road, barge and/or railroad access. From time to time, in connection with certain acquisitions, we engage a third party engineering firm to perform an aggregates reserves audit, but we do not perform annual reserve audits.

21

Including the Davenport Assets (as defined below) acquired in July 2015, we operate and currently have assets in 18 U.S. states and in British Columbia, Canada. The map below illustrates our geographic footprint:

Recent Developments

On August 5, 2015, we priced the offering of 19,500,000 shares of Summit Inc.’s Class A common stock at a price to the public of $25.75 per share. The underwriters have been granted a 30-day option to purchase up to an additional 2,925,000 shares of Class A common stock. The offering is expected to close on August 11, 2015, subject to customary closing conditions. Summit Inc. intends to use all of the net proceeds from the offering to purchase for cash 3,750,000 newly-issued LP Units from Summit Holdings and 15,750,000 outstanding LP Units from certain pre-IPO owners, including affiliates of the Sponsors and certain of our directors and officers. Summit Holdings intends to use the proceeds it receives to pay all or a portion of the $80.0 million deferred purchase price of Davenport Assets.

On July 17, 2015, we acquired certain assets from Lafarge, including a cement plant, a quarry and seven cement distribution terminals (the “Davenport Assets”) for a purchase price of $450.0 million in cash and a cement distribution terminal in Bettendorf, Iowa. We funded $370.0 million of the purchase price using proceeds from new senior notes and term debt issued by Summit LLC. The remaining $80.0 million of the purchase price is due to Lafarge no later than December 31, 2015 and accrues interest at an annual rate of 7.5%, payable monthly.

On July 8, 2015, we issued $350.0 million in aggregate principal amount of 6.125% senior notes due July 15, 2023 (the “2023 Notes”, collectively with the 2020 Notes, “Senior Notes”). The 2023 Notes were issued at 100% of their par value. Interest on the 2023 Notes is payable semi-annually on January 15 and July 15 of each year commencing on January 15, 2016.

On July 17, 2015, we refinanced our term loan under our senior secured credit facilities (the “Refinancing”). The Refinancing, among other things: (i) reduced the applicable margins used to calculate interest rates for term loans under our Senior Secured Credit Facilities to 3.25% for LIBOR rate loans and 2.25% for base rate loans, subject to a LIBOR floor of 1.00% (and one 25 basis point step down upon Summit LLC achieving a certain first lien net leverage ratio); (ii) increased term loans borrowed under our term loan facility to an aggregate $650.0 million; and (iii) created additional flexibility under the financial maintenance covenants, which are tested quarterly, by increasing the applicable maximum Consolidated First Lien Net Leverage Ratio, as defined in the credit agreement governing our senior secured credit facilities (the “Credit Agreement”).

We used the net proceeds from the 2023 Notes and the Refinancing to finance the initial $370.0 million cash purchase price for the Davenport Assets, to refinance our existing senior secured term loan facility, to redeem $183.0 million aggregate principal amount of our outstanding 2020 Notes and to pay related fees and expenses.

Business Trends and Conditions

The U.S. construction materials industry is composed of four primary sectors: aggregates; cement; ready-mixed concrete; and asphalt paving mix. Each of these materials is widely used in most forms of construction activity. Competition is limited in part by the distance materials can be transported efficiently, resulting in predominantly local or regional operations. Participants in these sectors

22

typically range from small, privately-held companies focused on a single material, product or market to multinational companies that offer a wide array of construction materials, products and related services. We estimate that approximately 65% of the aggregates in the United States are held by private companies.

Our revenue is derived from multiple end-use markets including private residential and nonresidential construction, as well as public infrastructure construction. Residential and nonresidential construction consists of new construction and repair and remodel markets. The construction sectors in the local economies in which we operate have begun to show signs of recovery. However, we could still be affected by any economic stagnation or decline, which could vary by local region and market. 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 housing starts, construction employment and highway obligations. All of these factors should result in increased construction activity in the private sector. However, we do not expect this recovery to be consistent across the United States. Certain of our markets are showing greater, more rapid signs of recovery. Increased construction activity in the private sector could lead to increased public infrastructure spending in the relatively near future. Public infrastructure includes spending by federal, state 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. Our acquisitions to date have been primarily focused in states with certain constitutional protections for transportation funding sources, which we believe limits our exposure to state and local budgetary uncertainties.

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 expired on September 30, 2014 and on August 1, 2014, a Highway Trust Fund extension bill was enacted. This bill provides funding that is expected to last through July 2015. On July 30, 2015 Congress passed a bill to extend funding through October 29, 2015. This bill also included provisions to raise approximately $8.0 billion in revenue to fund the program through the October 2015 extension. Any additional funding or successor programs have yet to be approved. With the nation’s infrastructure aging, we expect U.S. infrastructure spending to grow over the long term, and we believe we are well positioned to capitalize on any such increase.

In addition to federal funding, highway construction and maintenance funding is also available through state, county and local agencies. Our five largest states by revenue (Texas, Kansas, Kentucky, Utah and Missouri, which represented approximately 34%, 19%, 11%, 10% and 9%, respectively, of our total revenue in 2014) each have funds whose revenue sources have certain constitutional protections and are dedicated for transportation projects.

• Texas Department of Transportation’s budget from 2014 to 2016 is $25.3 billion.

• Kansas has a 10-year $8.2 billion highway bill that was passed in May 2010.

• Kentucky’s biennial highway construction plan has funding of $3.6 billion from July 2014 to June 2016.

• Utah’s transportation investment fund has $3.5 billion committed through 2018.

• Missouri has an estimated $0.7 billion in annual construction funding committed to essential road and bridge programs through 2017.

Within many of our markets, state and local governments have taken actions to maintain or grow highway funding during a time of uncertainty with respect to federal funding. For example:

• On November 4, 2014, voters in Texas passed a proposition that will provide $1.7 billion of incremental funding annually to the Texas Department of Transportation. The funds must be used for construction, maintenance, rehabilitation and acquiring right-of-way for public roads. The Texas legislature recently passed the largest two-year budget in the history of the Texas Department of Transportation (with growth in both new construction and maintenance). In addition, increased energy sector activity in parts of Texas has driven an increase in private construction demand, which we expect to continue. In particular, Houston and Austin, Texas have seen rapid residential demand expansion, which we expect to provide a stimulus for non-residential and public infrastructure demand, as job growth has drawn new residents.

• Increases in heavy truck registration fees, dedicated sales tax revenue and bond issuances have enabled Kansas to maintain stability in public infrastructure spending.

• We believe that public infrastructure spending in Kentucky, which comprises the majority of our revenue in the state, will remain consistent in the upcoming years.

• We expect primarily maintenance-related public demand in Utah and Missouri, both of which have recently completed large spending programs.

Use and consumption of our products fluctuate due to seasonality. Nearly all of the products used by us, and by our customers, in the private construction or public infrastructure industries are used outdoors. Our highway operations and production and distribution facilities are also located outdoors. Therefore, seasonal changes and other weather-related conditions, in particular extended rainy and cold weather in the spring and fall and major weather events, such as hurricanes, tornadoes, tropical storms 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-mixed 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. As a result of the contract escalation clauses and effective use of the firm purchase commitments, commodity prices did not have a material effect on our results of operations in the three and six months ended June 27, 2015 as compared to the three and six months ended June 28, 2014.

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.

Our paving and related services backlog represents our estimate of revenue that will be realized under the applicable contracts. We generally include a project in backlog at the time it is awarded and funding is in place. Many of our paving and related services are awarded and completed within one year and therefore may not be reflected in our beginning or ending contract backlog. Historically, we have not been materially adversely affected by contract cancellations or modifications. However, subject to applicable contract terms, substantially all contracts in our backlog may be cancelled or modified by our customers.

As a vertically-integrated business, approximately 25% of our aggregates sales volume was further processed and sold as a downstream product, such as ready-mixed concrete or asphalt paving mix, or used in our paving and related services business, and approximately 81% of the asphalt paving mix we sold was installed by our own paving crews during the six months ended June 27, 2015. The following table sets forth, our backlog as of the indicated dates:

	June 27,		June 28,
(in thousands)	2015		2014
Aggregate (in tons)		5,967		6,067
Asphalt (in tons)		2,578		2,815
Ready-mixed concrete (in cubic yards)		326		209
Construction services(1)	$	451,055	$	441,088

(1) The dollar value of the construction services backlog includes the value of the aggregate and asphalt tons and ready-mixed concrete cubic yards in backlog that are expected to be sourced internally.

Financial Highlights

The principal factors in evaluating our financial condition and operating results for the three and six months ended June 27, 2015 as compared to June 28, 2014 are:

• Net revenue increased $36.6 million and $75.7 million in the three and six months ended June 27, 2015, respectively, as a result of pricing and volume increases across our product lines, which includes volume contributions from our acquisitions.

24

• Our operating income increased $8.4 million and declined $15.6 million in the three and six months ended June 27, 2015, respectively. The improvement in operating income in the three months ended June 27, 2015 was driven by improved pricing as well as an increased proportion of sales generated by materials and products, as compared to services. In the six months ended June 27, 2015, our operating loss was affected by $28.3 million of costs incurred in conjunction with the IPO.

• In March 2015, we completed an IPO of Summit Inc.’s Class A common stock, the proceeds of which were used: (i) to redeem $288.2 million in aggregate principal amount of our outstanding 2020 Notes at a redemption price of 100% and an applicable premium thereon; (ii) to purchase a portion of the noncontrolling interests of Continental Cement; (iii) to pay a one-time fee of $13.8 million in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The redemption of the 2020 Notes occurred in April 2015.

Acquisitions

In addition to our organic growth, we continued to grow our business through acquisitions, completing the following transactions in 2015 and 2014:

• On July 17, 2015, we completed the acquisition of the Davenport Assets.

• On June 1, 2015, we acquired all of the issued and outstanding shares of Lewis & Lewis, Inc., a vertically integrated, aggregates-based business in Wyoming.

• On October 3, 2014, we purchased Concrete Supply, which included two sand and gravel sites and 10 ready-mixed concrete plants in Topeka and northeast Kansas, and a ready-mixed concrete plant in western Missouri.

• On September 30, 2014, we acquired all of the outstanding ownership interests in Colorado County S&G, a Texas limited liability company, M & M Gravel Sales, Inc., a Texas corporation, Marek Materials Co. Operating, Ltd., a Texas limited partnership, and Marek Materials Co., L.L.C., a Texas limited liability company, which collectively supply aggregates to the west Houston, Texas markets.

• On September 19, 2014, we acquired all of the membership interests of Southwest Ready Mix, which included two ready-mixed concrete plants and serves the downtown and southwest Houston, Texas markets.

• On September 4, 2014, we acquired all of the issued and outstanding shares and certain shareholder notes of Rock Head Holdings Ltd. and B.I.M. Holdings Ltd., which collectively indirectly owned all the shares of Mainland Sand and Gravel Ltd., a supplier of construction aggregates to the Vancouver metropolitan area based in Surrey, British Columbia.

• On July 29, 2014, we acquired all of the assets of Canyon Redi-Mix, Inc. The acquired assets include two ready-mixed concrete plants, which serve the Permian Basin region of West Texas.

• On June 9, 2014, we acquired all of the membership interests of Buckhorn Materials, LLC (“Buckhorn”), an aggregates quarry in South Carolina, and Construction Materials Group LLC, a sand pit in South Carolina.

• On March 31, 2014, we acquired all of the stock of Troy Vines, an integrated aggregates and ready-mixed concrete business headquartered in Midland, Texas, which serves the Permian Basin region of West Texas.

• On January 17, 2014, we acquired certain aggregates and ready-mixed concrete assets of Alleyton in Houston, Texas, which expands our presence in the Texas market.

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 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.

25

Operating income (loss) reflects our profit (loss) 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 costs 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 costs and depreciation, depletion, amortization and accretion have historically grown ratably with revenue. However, as volumes increase, we expect these costs, as a percentage of revenue, to decrease. Our transaction costs fluctuate with the number and size of acquisitions completed each year.

The table below includes revenue and operating income (loss) by segment for the three and six months ended June 27, 2015 and June 28, 2014.

	Three months ended										Six months ended

(1) Corporate results primarily consist of compensation and office expenses for employees included in the Company’s headquarters and, in the six months ended June 27, 2015, $28.3 million of costs associated with the March 2015 IPO.

Non-GAAP Performance Measures

The performance of our segments is evaluated based on several factors including a measure we call Adjusted EBITDA by segment. We define Adjusted EBITDA as net income (loss) from continuing operations before income taxes, interest expense, depreciation, depletion, amortization and accretion, loss on debt financings, IPO costs, stock compensation costs and transaction costs. Adjusted EBITDA is determined before considering the loss from discontinued operations, loss on debt financings and IPO costs, as these amounts are not viewed by management as part of our core business when assessing the performance of our segments or allocation of resources. Accretion expense is recognized on our asset retirement obligations and reflects the time value of money. Given that accretion is similar in nature to interest expense, it is treated consistently with interest expense, and is excluded from Adjusted EBITDA.

We also evaluate the performance of our business based on a metric we call Gross Profit, which we define as operating income (loss) before general and administrative expenses, depreciation, depletion, amortization and accretion and transaction costs. Adjusted EBITDA and Gross Profit are used by the chief operating decision maker, along with other factors, to allocate resources. These measures reflect an additional way of viewing aspects of our business that, when viewed with our results determined in accordance with U.S. GAAP and the accompanying reconciliations to U.S. GAAP financial measures included in the tables below, may provide a more complete understanding of factors and trends affecting our business. However, they should not be construed as being more important than other comparable U.S. GAAP measures and must be considered in conjunction with the U.S. GAAP measures. In addition, 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 interim financial statements in their entirety and not rely on any single financial measure.

(1) Gross margin, which we define as gross profit as a percentage of net revenue, improved 354 basis points and 322 basis points in the three and six months ended June 27, 2015, respectively, primarily as a result of a shift in product mix. Our acquisitions in 2014 were materials and products businesses. As a result, and as shown in the table below, gross revenue from aggregates and ready-mixed concrete was 23.7% and 28.5%, respectively, of total revenue in the six months ended June 27, 2015 compared to 19.2% and 23.9%, respectively, in the six months ended June 28, 2014. Gross revenue from paving and related services, which generally has lower operating margins than the materials and products, was 32.4% of total gross revenue in the six months ended June 27, 2015 compared to 42.2% in the six months ended June 28, 2014.

Net revenue increased $36.6 million and $75.7 million in the three and six months ended June 27, 2015, respectively, of which $20.1 million and $40.4 million was from increased sales of materials, respectively, and $19.8 million and $48.3 million was from increased sales of products, respectively, offset by a $3.4 million and $13.0 million decrease in service revenue, respectively. We had volume growth in our aggregates, cement and ready-mixed concrete lines of business, driven by the 2014 acquisitions and organic growth. We grew net revenue organically by $9.3 million and $16.0 million in the three and six months ended June 27, 2015, respectively.

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 by product includes intercompany and intracompany sales transferred at market value. The elimination of intracompany transactions is included in Other. Revenue from the liquid asphalt terminals is included in asphalt revenue.

Gross revenue for paving and related services decreased $7.6 million and $19.5 million in the three and six months ended June 27, 2015, respectively, primarily as a result of decreased activity in Texas, Utah and Kansas. Detail of our volumes and average selling prices by product in the six months ended June 27, 2015 and the six months ended June 28, 2014 were as follows:

	Six months ended				Six months ended
	June 27, 2015				June 28, 2014				Percentage Change in
	Volume (1)				Volume (1)
	(in thousands)		Pricing (2)		(in thousands)		Pricing (2)		Volume			Pricing

Ready-mixed concrete		1,564		101.91		1,197		95.04		30.7	%		7.2	%
Asphalt		1,598		56.58		1,647		52.49		(3.0	)%		7.8	%

(1) Volumes are shown in tons for aggregates, cement and asphalt and in cubic yards for ready-mixed concrete.

(2) Pricing is shown on a per ton basis for aggregates, cement and asphalt and on a per cubic yard basis for ready-mixed concrete.

Aggregates and ready-mixed concrete volumes were positively affected by the 2014 acquisitions. Aggregate pricing was affected by lower average prices in our Canadian business and product mix in the East region. In September 2014, we acquired Mainland in British Columbia, Canada. Mainland is an aggregates business supplying sand and gravel to the Vancouver metropolitan area. Approximately half of Mainland’s volumes (or 8% of total aggregate volumes) in the six months ended June 27, 2015 reflected sand sales, which has a lower average price than hard aggregates. As a result, the average price of our aggregates decreased 0.4% despite a 4.2% price increase in our organic operations.

Our cement volumes increased 8.9% and prices increased 9.2% both driven by increased demand in our markets. The ready-mixed concrete prices benefited from the increased cement pricing leading to a 7.2% increase in ready-mixed concrete pricing. Ready-mixed concrete volumes increased 30.7%, primarily driven by 2014 acquisitions in Texas and, to a lesser extent, in Kansas. Asphalt pricing increased 7.8%, while inclement weather resulted in a 3.0% decrease in volumes. The increased pricing was largely due to a shift in product mix. In 2014, asphalt volumes included a higher percentage of base materials. Prior to eliminations, the net effect of these volume and pricing changes on revenue was approximately $79.4 million and $21.0 million, respectively.

29

Operating income increased $8.4 million and decreased $15.6 million in the three and six months ended June 27, 2015, respectively, and Adjusted EBITDA improved $13.6 million and $24.1 million, respectively.

For the three months ended June 27, 2015 operating margin improved from 11.6% to 12.9%, which was attributable to the following:

Other	(1.1	)%
Operating margin — 2015	12.9	%

(1) As noted above, gross margin improved primarily due to a shift in product mix. Our acquisitions in 2014 were materials and products businesses. As a result, and as shown in the table above, gross revenue from aggregates and ready-mixed concrete was 21.9% and 24.5%, respectively, of total revenue in the three months ended June 27, 2015 compared to 18.4% and 22.0%, respectively, in the three months ended June 28, 2014. Gross revenue from paving and related services, which generally has lower operating margins than the materials and products, was 37.6% of total revenue in the three months ended June 27, 2015 compared to 44.7% in the three months ended June 28, 2014.

(3) Transaction costs increased $4.0 million in the three months ended June 27, 2015 due to the acquisition of the Davenport Assets consummated in July 2015.

For the six months ended June 27, 2015 operating margin decreased from (0.3)% to (3.3)%, which was attributable to the following:

Operating margin — 2014	(0.3	)%
IPO costs(1)	(5.6	)%
Gross margin(2)	3.2	%
Transaction costs	(0.4	)%
Other	(0.2	)%
Operating margin — 2015	(3.3	)%

(1) In conjunction with our March 2015 IPO, we recognized a $14.5 million charge on the modification of our share-based awards and a $13.8 million charge on the termination of a management fee agreement with our Sponsors. The management fee agreement was terminated on March 17, 2015.

(2) As noted above, gross margin improved primarily due to a shift in product mix. Our acquisitions in 2014 were materials and products businesses. As a result, and as shown in the table above, gross revenue from aggregates and ready-mixed concrete was 23.7% and 28.5%, respectively, of total revenue in the six months ended June 27, 2015 compared to 19.2% and 23.9%, respectively, in the six months ended June 28, 2014. Gross revenue from paving and related services, which generally has lower operating margins than the materials and products, was 32.4% of total revenue in the six months ended June 27, 2015 compared to 42.2% in the six months ended June 28, 2014.

(3) Transaction costs increased $2.7 million in the six months ended June 27, 2015 due to the acquisition of the Davenport Assets consummated in July 2015.

Other Financial Information

Loss on Debt Financings

In the three and six months ended June 27, 2015, we recognized a $30.9 million and $31.7 million, respectively, loss on debt financings related to the March 2015 amendment to the credit agreement and the April 2015 $288.2 redemption of 2020 Notes. On March 11, 2015, the Company entered into Amendment No. 3 to the Credit Agreement, which became effective on March 17, 2015 upon the consummation of the IPO. The amendment: (i) increased the size of the revolving credit facility from $150.0 million to $235.0 million; (ii) extended the maturity date of the revolving credit facility to March 11, 2020; (iii) amended certain covenants; and (iv) permits periodic tax distributions as contemplated in a tax receivable agreement, dated as of March 11, 2015, with Summit Holdings. In April 2015, using proceeds from the IPO, $288.2 million aggregate principal amount of the outstanding 2020 Notes were redeemed at a price equal to par plus an applicable premium. As a result of the redemption, a net charge of $31.3 million was recognized, which was composed of $38.2 million for the applicable prepayment premium and $4.7 million for the write-off of deferred financing fees, which was partially offset by an $11.6 million net benefit from the write-off the original issuance premium and discount.

30

Interest expense

Interest expense decreased $4.3 million in the three months ended June 27, 2015 due to the $288.2 million redemption of 2020 Notes in April 2015, partially offset by the additional $115.0 million of 2020 Notes issued in September 2014, which were outstanding for the entire duration of the three months ended June 27, 2015.

Income tax benefit

The income tax benefit increased $4.5 million and $8.4 million in the three and six months ended June 27, 2015, respectively, reflective of the tax benefit associated with the loss on debt financings that was recognized in our C corporations.

Net revenue in the West region increased approximately 15.6% and 21.6% in the three and six months ended June 27, 2015, respectively, due primarily to acquisitions and organic volume growth. Incremental net revenue from acquisitions totaled $19.7 million and $46.6 million in the three and six months ended June 27, 2015, respectively, and organic net revenue increased $5.5 million and $7.3 million, respectively. Gross revenue by product/service was as follows:

Gross revenue for paving and related services increased by $2.2 million and decreased $7.2 million in the three and six months ended June 27, 2015, respectively. The decrease in the six months ended June 27, 2015 was primarily a result of decreased activity in Texas due to inclement weather. The West region’s percent changes in sales volumes and pricing in the six months ended June 27, 2015 from the six months ended June 28, 2014 were as follows:

	Percentage Change in
	Volume			Pricing
Aggregates		78.9	%		1.1	%
Ready-mixed concrete		28.7	%		8.0	%
Asphalt		(4.2	)%		11.9	%

The increase in aggregates and ready-mixed concrete revenue was a result of increased volumes and pricing improvements from the 2014 acquisitions. Asphalt pricing increased 11.9%, while inclement weather resulted in a 4.2% decrease in volumes. The increased asphalt pricing was largely due to a shift in product mix. In 2014, asphalt volumes included a higher percentage of base materials. Prior to eliminations of intercompany transactions, the net effect of volume and pricing changes on revenue in the six months ended June 27, 2015 was approximately $58.5 million and $15.7 million, respectively.

The West region’s operating income increased $4.0 million and $8.9 million in the three and six months ended June 27, 2015, respectively, and Adjusted EBITDA improved $8.7 million and $18.8 million, respectively. The improvement was primarily driven by the inclusion of a half year of the 2014 acquisitions in the Houston and Midland/Odessa Texas and British Columbia, Canada markets and organic volume growth.

32

Operating margin in the three months ended June 27, 2015 was relatively consistent with operating margin in the three months ended June 28, 2014 as the Alleyton and Troy Vines acquisitions were fully included in the second quarter of 2014.

For the six months ended June 27, 2015 operating margin increased from 7.2% to 8.9%, which was attributable to the following:

Operating margin — 2014	7.2	%
Profit improvement(1)	1.7	%
Operating margin — 2015	8.9	%

(1) The operating margin improvement in the West region was primarily due to a shift in product mix. Our acquisitions in 2014 were materials and products businesses. As a result and as shown in the table above, gross revenue from aggregates and ready-mixed concrete was 21.2% and 36.9%, respectively, of total revenue in the six months ended June 27, 2015, compared to 14.7% and 33.4%, respectively, in the six months ended June 28, 2014. Gross revenue from paving and related services, which generally has lower operating margins than the materials and products, was 33.3% of total revenue in the six months ended June 27, 2015, compared to 44.5% in the six months ended June 28, 2014.

The $3.2 million and $5.4 million decrease in paving and related services was driven by decreased demand for our services in Kansas in the three and six months ended June 27, 2015, respectively. The Central region’s percent changes in sales volumes and pricing in the six months ended June 27, 2015 from the six months ended June 28, 2014 were as follows:

	Percentage Change in
	Volume			Pricing
Aggregates		9.7	%		2.5	%
Cement		8.9	%		9.2	%
Ready-mixed concrete		37.8	%		4.6	%
Asphalt		2.7	%		(2.2	)%

In 2015, volumes increased among all of the Central region’s product lines. The increase in aggregates, cement and ready-mixed concrete revenue were driven by both volume and pricing growth. Our cement volumes increased 8.9% and prices increased 9.2% both driven by increased demand in our markets. The ready-mixed concrete prices benefited from the increased cement pricing leading to a 4.6% increase in ready-mixed concrete pricing. Asphalt volumes increased 2.7%, while pricing decreased 2.2% due to lower commodity prices passed on to customers. Prior to eliminations of intercompany transactions, the net effect of volume and pricing changes on revenue in the six months ended June 27, 2015 was approximately $17.4 million and $5.3 million, respectively.

33

The Central region’s operating income increased $5.0 million and $4.7 million in the three and six months ended June 27, 2015, respectively, and Adjusted EBITDA improved $6.7 million and $7.8 million, respectively.

For the three months ended June 27, 2015 operating margin increased from 20.0% to 22.6%, which was attributable to the following:

Operating margin — 2014	20.0	%
Cement pricing improvements(1)	2.4	%
Other	0.2	%
Operating margin — 2015	22.6	%

(1) A $1.3 million curtailment benefit was recognized in 2014 related to a retiree postretirement benefit plan maintained for certain union employees at our cement plant, which was amended to eliminate all future retiree health and life coverage for the remaining union employees, effective January 1, 2014.

For the six months ended June 27, 2015 operating margin increased from 7.2% to 9.2%, which was attributable to the following:

Operating margin — 2014	7.2	%
2014 Curtailment benefit	(0.8	)%
Cement pricing improvements	4.3	%
Other	(1.5	)%
Operating margin — 2015	9.2	%

The $6.6 million and $6.9 million decrease in paving and related services was driven by decreased demand for our services in Kentucky in the three and six months ended June 27, 2015, respectively. The East region’s percent changes in sales volumes and pricing in the six months ended June 27, 2015 from the six months ended June 28, 2014 were as follows:

	Percentage Change in
	Volume			Pricing
Aggregates		27.8	%		0.1	%
Asphalt		(3.4	)%		1.3	%

Aggregate volumes in the East region increased 27.8% as a result of the Buckhorn Materials acquisition on April 1, 2014 and pricing increased 0.1%. Prior to eliminations of intercompany transactions, the net effect of volume and pricing changes on revenue in the six months ended June 27, 2015 was approximately $3.5 million and immaterial, respectively.

The East region’s operating income increased $2.8 million and $4.5 million in the three and six months ended June 27, 2015, respectively, and Adjusted EBITDA improved $1.6 million and $3.1 million, respectively. For the six months ended June 27, 2015 operating margin increased from (20.8)% to (9.9)%, which was primarily attributable to the increased aggregate volumes.

Liquidity and Capital Resources

Our primary sources of liquidity include cash on-hand, cash provided by operations and amounts available for borrowing under our credit facilities and capital-raising activities in the debt and capital markets. As of June 27, 2015, we had $12.6 million in cash and working capital of $66.0 million as compared to cash and working capital of $13.2 million and $80.4 million, respectively, at December 27, 2014. Working capital is calculated as current assets less current liabilities. There were no restricted cash balances as of

35

June 27, 2015 or December 27, 2014. Our remaining borrowing capacity on our senior secured revolving credit facility was $144.8 million as of June 27, 2015, which is net of $24.2 million of outstanding letters of credit, and is fully available to us within the terms and covenant requirements of our 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. For example, net cash used for operating activities in the six months ended June 28, 2014 was $45.9 million, compared to full year 2014 net cash provided by operating activities of $79.1 million. Net cash used for operating activities in the six months ended June 27, 2015 was $80.1 million.

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.

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 and interest coverage ratios. As of June 27, 2015, we were in compliance with all debt covenants.

At June 27, 2015 and December 27, 2014, $827.2 million and $1,064.9 million, respectively, of total debt, without giving effect to original issuance discount or premium, were outstanding under our respective debt agreements. Summit LLC has credit facilities that provide for term loans in an aggregate amount of $422.0 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, do not guarantee the Senior Notes. Summit LLC has pledged substantially all of its assets as collateral for the Senior Secured Credit Facilities. Summit LLC and its indirect wholly-owned subsidiary, Finance Corp, have issued $625.0 million aggregate principal amount of 2020 Notes due January 31, 2020 under an indenture dated as of January 30, 2012 (as amended and supplemented, the “Indenture”). We initially issued $250.0 million of 2020 Notes on January 30, 2012. We issued an additional $260.0 million and $115.0 million of 2020 Notes on January 17, 2014 and September 8, 2014, respectively, at a premium over par value, receiving aggregate proceeds of $409.3 million, before payment of fees and expenses. The proceeds from the January and September 2014 issuances were used for the purchases of Alleyton and Mainland, to make payments on the senior secured revolving credit facility and for general corporate purposes.

On July 8, 2015, we issued $350.0 million in aggregate principal amount of 6.125% senior notes due July 15, 2023. The 2023 Notes were issued at 100.0% of their par value. Interest on the 2023 Notes is payable semi-annually on January 15 and July 15 of each year commencing on January 15, 2016.

On July 17, 2015, we refinanced our term loan under the Senior Secured Credit Facilities. The Refinancing, among other things: (i) reduced the applicable margins used to calculate interest rates for term loans under our Senior Secured Credit Facilities to 3.25% for LIBOR rate loans and 2.25% for base rate loans, subject to a LIBOR floor of 1.00% (and one 25 basis point step down upon Summit LLC achieving a certain first lien net leverage ratio); (ii) increased term loans borrowed under our term loan facility to an aggregate $650.0 million; and (iii) created additional flexibility under the financial maintenance covenants, which are tested quarterly, by increasing the applicable maximum Consolidated First Lien Net Leverage Ratio (as defined in our Credit Agreement).

We used the net proceeds from the Notes and the Refinancing to finance the initial $370.0 million cash purchase price for the Davenport Acquisition, to refinance our existing senior secured term loan facility, to redeem $183.0 million aggregate principal amount of our outstanding 2020 Notes and to pay related fees and expenses. The $183.0 million redemption of 2020 Notes occurred on August 3, 2015.

Cash Flows

The following table summarizes our net cash used for or provided by operating, investing and financing activities and our capital expenditures in the six months ended June 27, 2015 and June 28, 2014:

Financing activities		132,032			329,153
Cash paid for capital expenditures	$	(43,379	)	$	(49,260	)

Operating activities

During the six months ended June 27, 2015, cash used in operating activities was $80.1 million primarily as a result of:

• Net loss of $79.8 million, adjusted for $64.9 million of non-cash expenses, including $57.1 million of depreciation, depletion, amortization and accretion and $17.0 million of share-based compensation expense.

• $16.6 million utilized to increase inventory consistent with the seasonality of our business for which our inventory levels typically decrease in the fourth quarter in preparation for the winter slowdown and are then increased during the first half of the year in preparation for the increased sales volumes in the spring and summer.

• $7.9 million associated with the timing of payments associated with accounts payable and accrued expenses in conjunction with the build-up of inventory levels and incurrence of repairs and maintenance costs to ready the business for increased sales volumes in the summer and fall. Almost all of our products are consumed and services provided outdoors. Our highest sales and earnings are normally in the spring, summer and fall months, primarily in the second and third quarters, and our lowest sales are in the winter months of the first and fourth quarters. Accordingly, during the winter months, particularly in the first quarter, our payments on accounts payable and accrued expenses outstanding from the prior year-end typically exceed new accounts payable and accrued expenses generated during the quarter, resulting in a net cash outflow. In addition, we made $49.3 million of interest payments in the six months ended June 27, 2015.

• $36.0 million of increased accounts receivable (billed and unbilled) 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.

During the six months ended June 28, 2014, cash used in operating activities was $45.9 million primarily as a result of:

• Net loss of $38.9 million, adjusted for $44.9 million of non-cash expenses, including $43.3 million of depreciation, depletion, amortization and accretion.

• $39.2 million of increased accounts receivable (billed and unbilled) consistent with the seasonality of our business.

• $17.8 million utilized to increase inventory consistent with the seasonality of our business.

• $7.9 million associated with the timing of payments associated with accounts payable and accrued expenses in conjunction with the build-up of inventory levels and incurrence of repairs and maintenance to prepare the business for increased sales volumes in the summer and fall. In addition, we paid $25.9 million of interest payments in the six months ended June 28, 2014.

Investing activities

During the six months ended June 27, 2015, cash used for investing activities was $52.6 million, of which $43.4 million was invested in capital expenditures and $15.9 million related to the 2015 acquisition of Lewis & Lewis, Inc., which was partially offset by $6.0 million of proceeds from asset sales.

37

During the six months ended June 28, 2014, cash used for investing activities was $277.4 million, $234.9 million of which related to the 2014 acquisitions of Alleyton, Troy Vines and Buckhorn Materials. In addition, we invested $49.3 million in capital expenditures, offset by $6.0 million of proceeds from asset sales. Approximately $12.2 million of the capital expenditures were invested in our cement business in Hannibal, Missouri, for continued development of an underground mine ($4.1 million), as well as improvements made to the cement plant during the annual scheduled winter shutdown in February 2014.

Financing activities

During the six months ended June 27, 2015, cash provided by financing activities was $132.0 million, which was primarily composed of $460.0 million of proceeds from Summit Inc.’s IPO. Summit Inc. sold 25.6 million shares of Common Stock in the first quarter of 2015, receiving $424.0 million of proceeds, net of underwriter and other issuance costs. Summit Inc. utilized $35.0 million of the proceeds for the purchase of the noncontrolling interest of Continental Cement. The remaining proceeds were contributed to Summit LLC to redeem $288.2 million aggregate principal amount of the outstanding 2020 Notes at a redemption price equal to par plus an applicable premium of $38.2 million and $5.2 million of accrued and unpaid interest. We also made $12.0 million of payments on acquisition related liabilities and paid $5.1 million in debt issuance costs

During the six months ended June 28, 2014, cash provided by financing activities was $329.2 million, which was primarily composed of $315.5 million of net additional borrowings, $282.8 million of which were the net proceeds from the January 2014 issuance of $260.0 million 2020 Notes issued at a premium of $22.8 million. Approximately $182.5 million of the funds from the borrowings were used to purchase Alleyton. The remaining funds have been used to fund working capital needs. In addition, we received equity contributions of $24.4 million and made $4.3 million of payments on acquisition related liabilities in the six months ended June 28, 2014.

Cash paid for capital expenditures

We expended approximately $43.4 million in capital expenditures in the six months ended June 27, 2015 compared to $49.3 million in the six months ended June 28, 2014. The 2015 capital expenditures were primarily composed of various pieces of equipment and rolling stock.

We estimate that we will invest between $80.0 million and $90.0 million in capital expenditures in 2015, which we have funded or expect to fund through cash on hand, cash from operations, outside financing arrangements and available borrowings under our Senior Secured Credit Facilities. In 2015, we expect to continue investing in Texas, including approximately $6.4 million on installation of a new sand and gravel processing plant near Houston and $7.0 million on installation of a new asphalt plant in San Antonio.

Contractual Obligations

The table below presents, as of June 27, 2015, our obligations and commitments to make future payments under contracts and contingent commitments. The information below does not give effect to the redemption of $183.0 million of 2020 Notes that occurred on August 3, 2015, the new borrowings from the Refinancing in connection with the acquisitions of the Davenport Assets and the offering of the 2023 Notes or the use of proceeds therefrom.

(1) Future interest payments were calculated using the applicable fixed and floating rates charged by our lenders in effect as of June 27, 2015 and may differ from actual results.

(2) Amounts represent estimated future payments to fund our defined benefit plans.

(3) Amounts represent purchase commitments entered into in the normal course of business, primarily for fuel purchases. Commitments are generally less than one year.

(4) Upon the consummation of the Reorganization, the Company entered into a tax receivable agreement with the holders of LP Units and certain other indirect pre-IPO owners (“Investor Entities”) that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result of (i) increases in tax basis of the tangible and intangible assets of Summit Holdings resulting from future exchanges of LP Units for shares of Class A common stock and (ii) the utilization of certain net operating losses of the Investor Entities and certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. We estimated that, as of the IPO date, and assuming that Summit Materials, Inc. had exercised its termination right associated with this benefit immediately following the IPO, the aggregate amount of the termination payments would be approximately $461.0 million. Estimating the amount of payments that may be made under the tax receivable agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors. The increases in tax basis as a result of an exchange, as well as the amount and timing of any payments under the tax receivable agreement, will vary depending upon a number of factors. As of June 27, 2015, no LP units had been exchanged.

In addition to the tax receivable agreement, the holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Inc.’s estimate of the net taxable income of Summit Holdings allocated to each holder of LP Units multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate applicable to an individual or corporate resident in New York, New York (or a corporate resident in certain circumstances). We estimate the cash tax distribution payments to be $20.8 million for the remainder of 2015, $21.5 million in 2016 and $12.6 million in 2017. Estimating the tax distributions required under the limited partnership agreement is imprecise by its nature as the calculation depends on a variety of factors, including, but not limited to, projected taxable income of Summit Holdings and changes in ownership as a result of LP Units exchanges for shares of Class A common stock.

Commitments and contingencies

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

39

We are obligated under an indemnification agreement entered into with the sellers of Harper Contracting, Inc., Harper Sand and Gravel, Inc., Harper Excavating, Inc., Harper Ready Mix Company, Inc. and Harper Investments, Inc. (collectively, “Harper”) for the sellers’ 40% ownership interests in a joint venture agreement. We have the rights to any benefits under the joint venture as well as the assumption of any obligations, but do not own equity interests in the joint venture. The joint venture incurred significant losses on a highway project in Utah, which resulted in requests for funding from the joint venture partners and, ultimately, from us. Through June 27, 2015, we have funded $8.8 million, of which $4.0 million was funded in 2012 and $4.8 million was funded in 2011. On April 2, 2015, the Utah Department of Transportation filed suit in the Fourth District Court of Utah County, Utah against the joint venture and the parties to the joint venture seeking damages of at least $29.4 million. As of June 27, 2015 and December 27, 2014, an accrual of $4.3 million was recorded in other noncurrent liabilities as our best estimate of loss related to this matter.

We are obligated under various firm purchase commitments for certain raw materials and services that are in the ordinary course of business. The terms of these agreements are generally less than one year. 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 position, results of operations or liquidity of the Company.

Off-Balance sheet arrangements

As of June 27, 2015, we had no material off-balance sheet arrangements.

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 Prospectus.

Exhibit 95.1

Mine Safety Disclosures

The operation of Summit Materials, Inc.’s and its subsidiaries’ (collectively, the “Company”) aggregates quarries and mines is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). MSHA inspects the Company’s quarries and mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders may be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), the Company is required to present information regarding certain mining safety and health citations which MSHA has issued with respect to its aggregates mining operations in its periodic reports filed with the Securities and Exchange Commission (the “SEC”). In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the quarry or mine and types of operations (underground or surface); (ii) the number of citations issued will vary from inspector to inspector and location to location; and (iii) citations and orders can be contested and appealed, and in that process, may be reduced in severity and amount, and are sometimes dismissed.

The Company presents the following items regarding certain mining safety and health matters for the three months ended June 27, 2015, as applicable:

• Total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under Section 104 of the Mine Act for which the Company has received a citation from MSHA (hereinafter, “Section 104 S&S Citations”). If MSHA determines that a violation of a mandatory health or safety standard is likely to result in a reasonably serious injury or illness under the unique circumstance contributed to by the violation, MSHA will classify the violation as a “significant and substantial” violation (commonly referred to as a “S&S” violation). MSHA inspectors will classify each citation or order written as a “S&S” violation or not.

• Total number of orders issued under Section 104(b) of the Mine Act (hereinafter, “Section 104(b) Orders”). These orders are issued for situations in which MSHA determines a previous violation covered by a Section 104(a) citation has not been totally abated within the prescribed time period, so a further order is needed to require the mine operator to immediately withdraw all persons (except authorized persons) from the affected area of a quarry or mine.

• Total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under Section 104(d) of the Mine Act (hereinafter, “Section 104(d) Citations and Orders”). These violations are similar to those described above, but the standard is that the violation could significantly and substantially contribute to the cause and effect of a safety or health hazard, but the conditions do not cause imminent danger, and the MSHA inspector finds that the violation is caused by an unwarranted failure of the operator to comply with the health and safety standards.

• Total number of flagrant violations under Section 110(b)(2) of the Mine Act (hereinafter, “Section 110(b)(2) Violations”). These violations are penalty violations issued if MSHA determines that violations are “flagrant”, for which civil penalties may be assessed. A “flagrant” violation means a reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury.

• Total number of imminent danger orders issued under Section 107(a) of the Mine Act (hereinafter, “Section 107(a) Orders”). These orders are issued for situations in which MSHA determines an imminent danger exists in the quarry or mine and results in orders of immediate withdrawal of all persons (except certain authorized persons) from the area of the quarry or mine affected by its condition until the imminent danger and the underlying conditions causing the imminent danger no longer exist.

• Total dollar value of proposed assessments from MSHA under the Mine Act. These are the amounts of proposed assessments issued by MSHA with each citation or order for the time period covered by the reports. Penalties are assessed by MSHA according to a formula that considers a number of factors, including the mine operator’s history, size, negligence, gravity of the violation, good faith in trying to correct the violation promptly, and the effect of the penalty on the operator’s ability to continue in business.

• Total number of mining-related fatalities. Mines subject to the Mine Act are required to report all fatalities occurring at their facilities unless the fatality is determined to be “non-chargeable” to the mining industry. The final rules of the SEC require disclosure of mining-related fatalities at mines subject to the Mine Act. Only fatalities determined by MSHA not to be mining-related may be excluded.

• Receipt of written notice from MSHA of a pattern (or a potential to have such a pattern) of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of other mine health or safety hazards under Section 104(e) of the Mine Act. If MSHA determines that a mine has a “pattern” of these types of violations, or the potential to have such a pattern, MSHA is required to notify the mine operator of the existence of such a thing.

• Legal actions before the Federal Mine Safety and Health Review Commission (the “Commission”) pending as of the last day of period.

• Legal actions before the Commission initiated during period.

• Legal actions before the Commission resolved during period.

The Commission is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. The cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under Section 105 of the Mine Act. There were no legal actions pending before the Commission for any of the Company’s quarries and mines, as of or during the quarter ended June 27, 2015.

SUMMIT MATERIALS, LLC

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(Tables in thousands)

1. SUMMARY OF ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Summit Materials, LLC (“Summit LLC”) is a vertically integrated, construction materials company. Through its subsidiaries, it is engaged in the production and sale of aggregates, cement, ready-mixed concrete, asphalt paving mix and concrete products. Summit LLC, through its subsidiaries (collectively, the “Company”), owns and operates quarries, sand and gravel pits, a cement plant, cement distribution terminals, ready-mixed concrete plants, asphalt plants and landfill sites. It is also engaged in paving and related services. The Company is organized by geographic region and has three operating segments, which are also its reporting segments: the West; Central; and East regions.

Substantially all of the Company’s 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 and to cyclical changes in construction spending, among other factors.

Summit LLC is a wholly owned indirect subsidiary of Summit Materials Holdings L.P. (“Summit Holdings”), whose major indirect owners are certain investment funds affiliated with Blackstone Capital Partners V L.P. and Silverhawk Summit, L.P. and Summit Materials, Inc. (“Summit Inc.”). Summit Inc. was formed as a Delaware corporation on September 23, 2014 to be a holding company. Its sole asset is a controlling equity interest in Summit Holdings. Pursuant to a reorganization into a holding company structure (the “Reorganization”) in connection with Summit Inc.’s March 2015 initial public offering (“IPO”), Summit Inc. became a holding corporation operating and controlling all of the business and affairs of Summit Holdings and its subsidiaries, including Summit LLC.

Summit Inc. commenced operations on March 11, 2015 upon the pricing of the initial public offering of its Class A common stock (“IPO”). Summit Inc. raised $433.0 million, net of underwriting discounts, through the issuance of 25,555,555 shares of Class A common stock at a public offering price of $18.00 per share. Summit Inc. used the offering proceeds to purchase a number of newly-issued Class A Units (“LP Units”) from Summit Holdings equal to the number of shares of Class A common stock issued to the public. Summit Inc. caused Summit Holdings to use these proceeds: (i) to redeem $288.2 million in aggregate principal amount of outstanding 10  ¹⁄₂% Senior Notes due January 31, 2020 (“2020 Notes”) at a redemption price of 100% and an applicable premium thereon; (ii) to purchase 71,428,571 Class B Units of Continental Cement Company, L.L.C. (“Continental Cement”); (iii) to pay a one-time termination fee of $13.8 million primarily to affiliates of the Sponsors in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The $288.2 million redemption of 2020 Notes was completed in the second quarter of 2015 at a redemption price equal to par plus an applicable premium of $38.2 million plus $5.2 million of accrued and unpaid interest.

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. 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 27, 2014. The Company continues to follow the accounting policies set forth in those 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 June 27, 2015, the results of operations for the three and six months ended June 27, 2015 and June 28, 2014 and cash flows for the six months ended June 27, 2015 and June 28, 2014.

The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The 53-week year occurs approximately once every seven years and will occur in 2015. The additional week in the 53-week year will be included in the fourth quarter.

The consolidated financial statements of the Company include the accounts of Summit LLC and its subsidiaries, including noncontrolling interests. All significant intercompany balances and transactions have been eliminated. Noncontrolling interests in consolidated subsidiaries represent a 20% ownership in Ohio Valley Asphalt, LLC and, prior to the IPO and concurrent purchase of the noncontrolling interests of Continental Cement Company, L.L.C. (“Continental Cement”), a 30% redeemable ownership in Continental Cement.

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

6

reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, 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. Management adjusts such estimates and assumptions when circumstances dictate. 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—As of June 27, 2015, the Company’s operations are conducted primarily across 17 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Kansas, Kentucky, Utah and Missouri. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers, and management does not believe that any significant concentrations of credit exist with respect to individual customers or groups of customers. No single customer accounted for more than 10% of total revenue in the three and six months ended June 27, 2015 and June 28, 2014.

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. Contingent consideration as of June 27, 2015 and December 27, 2014 was:

	June 27,		December 27,
	2015		2014
Current portion of acquisition-related liabilities:
Current portion of contingent consideration	$	4,486	$	2,375
Acquisition- related liabilities:
Contingent consideration	$	4,193	$	5,379

The fair values are based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% 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. There were no material valuation adjustments to contingent consideration obligations in the three or six months ended June 27, 2015 or June 28, 2014.

7

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 June 27, 2015 and December 27, 2014 was:

	June 27, 2015				December 27, 2014
	Fair Value		Carrying Value		Fair Value		Carrying Value
Level 2
Long-term debt(1)	$	780,155	$	827,247	$	1,101,873	$	1,064,917
Level 3
Current portion of deferred consideration and noncompete obligations(2)		15,409		15,409		16,027		16,027
Long term portion of deferred consideration and noncompete obligations(3)		30,309		30,309		37,357		37,357

(1) $5.3 million included in current portion of debt as of June 27, 2015 and December 27, 2014. Excludes $66.0 million outstanding on the revolving credit facility as of June 27, 2015.

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

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

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.

Redeemable Noncontrolling Interest— On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit LLC. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 of Summit Inc.’s Class A common shares and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016. The notes payable is a liability of Summit Holdings and, is therefore not included in the liabilities of Summit LLC.

New Accounting Standards — In April 2015, the FASB issued a new accounting standard to simplify the presentation of debt issuance costs. Accounting Standards Update (“ASU”) 2015-03,Simplifying the Presentation of Debt Issuance Costs, changes the presentation of debt issuance costs in financial statements. Under the ASU, an entity will present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The guidance will be applied retrospectively to all prior periods (i.e., the balance sheet for each period will be adjusted). Had the Company adopted this guidance as of the current period, both Other Assets (noncurrent) and Long-term Debt as of June 27, 2015 and December 27, 2014, would have decreased by $11.8 million and $16.8 million, respectively.

In April 2015, the FASB issued a new accounting standard, ASU 2015-04,Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets, which gives an employer whose fiscal year-end does not coincide with a calendar month-end (e.g., an entity that has a 52- or 53-week fiscal year) the ability, as a practical expedient, to measure defined benefit retirement obligations and related plan assets as of the month-end that is closest to its fiscal year-end. The ASU is effective for public business entities for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early application is permitted, and the ASU should be applied prospectively. The Company does not expect the adoption of this ASU to have a material effect on its financial position or results of operations.

In May 2014, the FASB issued a new accounting standard to improve and converge the financial reporting requirements for revenue from contracts with customers. ASU No. 2014-09,Revenue from Contracts with Customers, prescribes a five-step model for revenue recognition that will replace most existing revenue recognition guidance in U.S. GAAP. The ASU will supersede 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

8

changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB decided to delay the effective date of the new revenue standard by one year, or to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements.

Reclassifications— Certain amounts in the prior year have been reclassified to conform to the presentation in the consolidated financial statements as of and for the three and six months ended June 27, 2015.

2. REORGANIZATION

Prior to the IPO and Reorganization, the capital structure of Summit Holdings consisted of six different classes of limited partnership interests (Class A-1, Class A-2, Class B-1, Class C, Class D-1 and Class D-2), each of which was subject to unique distribution rights. There were no outstanding Class A-2 interests. In connection with the IPO and the Reorganization, the limited partnership agreement of Summit Holdings was amended and restated to, among other things, modify its capital structure by creating a single new class of units (the “LP Units”), referred to as the “Reclassification.” Immediately following the Reclassification, 69,007,297 LP Units were outstanding. In addition, in substitution for part of the economic benefit of the Class C and Class D interests that was not reflected in the conversion of such interests to LP Units, warrants were issued to holders of Class C interests to purchase an aggregate of 160,333 shares of Class A common stock, and options were issued to holders of Class D interests to purchase an aggregate of 4,358,842 shares of Class A common stock (“leverage restoration options”). In each case, the exercise price of such warrants and leverage restoration options was the IPO price of $18.00 per share. In conjunction with the Reclassification of the equity-based awards, the Company recognized $14.5 million modification charge in general and administrative costs in the three months ended March 28, 2015.

2020 Notes—The 2020 Notes were issued under an indenture dated January 30, 2012 (as amended and supplemented, the “Indenture”). The 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

10

certain investments, sell or transfer certain assets, create liens, consolidate, merge, sell or otherwise dispose of all or substantially all of the Company’s assets, enter into certain transactions with affiliates, and designate subsidiaries as unrestricted subsidiaries. The Indenture also contains customary events of default. As of June 27, 2015 and December 27, 2014, the Company was in compliance with all covenants. Interest on the 2020 Notes is payable semi-annually in arrears.

In April 2015, using proceeds from the IPO, $288.2 million aggregate principal amount of the outstanding 2020 Notes were redeemed at a price equal to par plus an applicable premium. As a result of the redemption, a net charge of $31.3 million was recognized, which was composed of $38.2 million for the applicable prepayment premium and $4.7 million for the write-off of deferred financing fees, which was partially offset by an $11.6 million net benefit from the write-off the original issuance premium and discount.

On September 8, 2014 and January 17, 2014, the Issuers issued an additional $115.0 million and $260.0 million, respectively, aggregate principal amount of 2020 Notes (the “Additional Notes”), receiving proceeds of $409.3 million, before payment of fees and expenses and including an aggregate $34.3 million premium. The proceeds from the sale of the Additional Notes were used for the purchases of acquisitions, to make payments on the revolving credit facility and for general corporate purposes. The Additional Notes are treated as a single series with the $250.0 million of 2020 Notes (the “Existing Notes”) and have substantially the same terms as those of the Existing Notes. The Additional Notes and the Existing Notes are treated as one class under the Indenture.

Senior Secured Credit Facilities— Summit LLC has credit facilities which provide for term loans in an aggregate amount of $422.0 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 term debt are due on the last business day of each March, June, September and December. The unpaid principal balance was due in full on the maturity date, which was January 30, 2019. In July 2015, the outstanding balance of the terms loans was refinanced, extending the maturity date to 2022. See further discussion of this refinancing in note 14, Subsequent Events.

On March 11, 2015, the Company entered into Amendment No. 3 to the credit agreement governing the Senior Secured Credit Facilities, which became effective on March 17, 2015 upon the consummation of the IPO. The amendment: (i) increased the size of the revolving credit facility from $150.0 million to $235.0 million; (ii) extended the maturity date of the revolving credit facility to March 11, 2020; (iii) amended certain covenants; and (iv) permits periodic tax distributions as contemplated in a tax receivable agreement, dated as of March 11, 2015, with Summit Holdings. As a result of this amendment, $0.4 million of financing fees were charged to earnings in the six months ended June 27, 2015.

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 2.5% 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 3.5% for LIBOR rate loans. The interest rate in effect at June 27, 2015 was 3.6%.

There were $66.0 of outstanding borrowings under the revolving credit facility as of June 27, 2015, leaving remaining borrowing capacity of $144.8 million, which is net of $24.2 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 must adhere to certain financial covenants related to its debt and interest leverage ratios, as defined in the Senior Secured Credit Facilities. The consolidated first lien net leverage ratio, reported each quarter, should be no greater than 4.5:1.0. The interest coverage ratio must be at least 1.70:1.0 from January 1, 2013 through December 31, 2014 and 1.85:1.0 thereafter. As of March 27, 2015 and December 27, 2014, the Company was in compliance with all covenants. Summit LLC’s wholly-owned domestic subsidiary companies are subject to certain exclusions and exceptions are named as subsidiary guarantors of the 2020 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.

Interest expense related to debt totaled $14.8 million and $36.8 million for the three and six months ended June 27, 2015, respectively, and $19.3 million and $36.5 million for the three and six months ended June 28, 2014, respectively. The following table presents the activity for the deferred financing fees for the six months ended June 27, 2015 and June 28, 2014:

8. INCOME TAXES

Summit LLC is a limited liability company and passes its tax attributes for federal and state tax purposes to its parent company and is generally not subject to federal or state income tax. However, certain subsidiary entities file federal and state income tax returns due to their status as C corporations. The provision for income taxes is primarily composed of federal, state and local income taxes for the subsidiary entities that have C corporation status.

The effective income tax rate for these entities differs from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates and (3) certain non-recurring items, such as differences in the treatment of transaction costs, which are often not deductible for tax purposes.

As of June 27, 2015 and December 27, 2014, the Company has 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 for the three or six months ended June 27, 2015 and June 28, 2014.

Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to each holder of LP Units multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate applicable to an individual or corporate resident in New York, New York (or a corporate resident in certain circumstances). In the three and six months ended June 27, 2015, the Company declared distributions totaling $16.4 million, $11.8 million were paid in cash to Summit Holdings, who, in turn, distributed the fund to its partners, excluding Summit Inc., and $4.6 million was paid to Summit Holdings, who, in turn, paid Summit Inc. in July 2015.

9. 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’s policy is to record legal fees as incurred.

Litigation and Claims—The Company is obligated under an indemnification agreement entered into with the sellers of Harper Contracting, Inc., Harper Sand and Gravel, Inc., Harper Excavating, Inc., Harper Ready Mix Company, Inc. and Harper Investments, Inc. (collectively, “Harper”) for the sellers’ 40% ownership interests in a joint venture agreement. The Company has the rights to any benefits under the joint venture as well as the assumption of any obligations, but does not own equity interests in the joint venture. The joint venture incurred significant losses on a highway project in Utah, which resulted in requests for funding from the joint venture partners and, ultimately, from the Company. Through June 27, 2015, the Company has funded $8.8 million, of which $4.0 million was funded in 2012 and $4.8 million was funded in 2011. On April 2, 2015, the Utah Department of Transportation filed suit in the Fourth District Court of Utah County, Utah against the joint venture and the parties to the joint venture seeking damages of at least $29.4 million. As of June 27, 2015 and December 27, 2014, an accrual of $4.3 million was recorded in other noncurrent liabilities as management’s best estimate of loss related to this matter.

During the ordinary course of business, there may be revisions to project costs and conditions that can give rise to change orders on construction contracts. Revisions can also result in claims made against a customer or subcontractor to recover project variances that have not been satisfactorily addressed through change orders with a customer. As of June 27, 2015 and December 27, 2014, the Company had unapproved change orders and claims of $1.4 million ($1.2 million in accounts receivable and $0.2 million in costs and estimated earnings in excess of billings) and $3.9 million ($1.2 million in accounts receivable, $0.5 million in costs and estimated earnings in excess of billings and $2.2 million in other assets), respectively.

Environmental Remediation—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 position, results of operations or liquidity in the future.

Other—In the ordinary course of business, the Company enters into various firm purchase commitments for certain raw materials and services. The terms of the purchase commitments are generally less than one year. 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 position, results of operations or liquidity of the Company.

12. RELATED PARTY TRANSACTIONS

Under the terms of a transaction and management fee agreement between Summit Holdings and Blackstone Management Partners L.L.C. (“BMP”), whose affiliates include controlling stockholders of the Summit Inc., BMP provided monitoring, advisory and consulting services to the Company through March 17, 2015. Under the terms of the agreement, BMP was permitted to assign, and had assigned, a portion of the fees to which it is entitled to Silverhawk Summit, L.P. and to certain other equity investors.

The management fee was calculated based on the greater of $300,000 or 2.0% of the Company’s annual consolidated profit, as defined in the agreement, which are included in general and administrative expenses. The Company incurred management fees due to BMP totaling $1.0 million during the period between December 28, 2014 and March 17, 2015 and $1.3 million and $2.3 million in the three and six months ended June 28, 2014, respectively. During these periods, the Company paid immaterial amounts to Silverhawk Summit, L.P. and to other equity investors.

Also under the terms of the transaction and management fee agreement, BMP undertook financial and structural analysis, due diligence investigations, corporate strategy and other advisory services and negotiation assistance related to acquisitions for which the Company paid BMP transaction fees equal to 1.0% of the aggregate enterprise value of any acquired entity or, if such transaction was structured as an asset purchase or sale, 1.0% of the consideration paid for or received in respect of the assets acquired or disposed. The Company paid BMP $0.6 million and $2.3 million during the three and six months ended June 28, 2014, respectively. During these periods, the Company paid immaterial amounts to Silverhawk Summit, L.P. and to other equity investors. The acquisition-related fees paid pursuant to this agreement are included in transaction costs.

In connection with the IPO, the transaction and management fee agreement with BMP was terminated on March 17, 2015 for a final payment of approximately $13.8 million, $13.4 million was paid to affiliates of Blackstone and the remaining $0.4 million was paid to affiliates of Silverhawk Summit, L.P. and to certain other equity investors.

On April 16, 2015, the Company entered into an agreement with Lafarge North America Inc. (“Lafarge”) to purchase certain assets, including a cement plant, a quarry and seven cement distribution terminals (the “Davenport Assets”) for a purchase price of $450.0 million cash and a cement distribution terminal in Bettendorf, Iowa. At closing, $370.0 million of the purchase price was due and the remaining $80.0 million is due to the seller no later than December 31, 2015. Summit Holdings entered into a commitment letter dated April 16, 2015, with Blackstone Capital Partners V L.P. (“BCP”) for equity financing up to $90.0 million in the form of a preferred equity interest (the “Equity Commitment Financing”). The proceeds of the Equity Commitment Financing would be used to pay the $80.0 million deferred purchase price associated with the Davenport acquisition if a public offering of Summit Inc.’s Class A common stock cannot be effected by December 31, 2015. Summit Holdings paid a $1.8 million commitment fee to BCP in the six months ended June 27, 2015.

Blackstone Advisory Partners L.P., an affiliate of Blackstone, served as an initial purchaser of $5.75 million and $13.0 million principal amount of the 2020 Notes issued in September 2014 and January 2014, respectively, and received compensation in connection therewith.

Cement sales to companies owned by a former noncontrolling member of Continental Cement were approximately $1.4 million during the period between December 28, 2014 and March 11, 2015 and $4.5 million and $6.2 million during the three and six months ended June 28, 2014, respectively.

Summit LLC’s domestic wholly-owned subsidiary companies other than Finance Corp. (the “Guarantors”) are named as guarantors (collectively, the “Guarantors”) of the 2020 Notes. Certain other partially-owned subsidiaries and a non-U.S. entity do not guarantee the 2020 Notes (collectively, the “Non-Guarantors”). The Guarantors provide a joint and several, full and unconditional guarantee of the 2020 Notes.

There are no significant restrictions on Summit LLC’s ability to obtain funds from any of the Guarantor Subsidiaries in the form of dividends or loans. Additionally, there are no significant restrictions on a Guarantor Subsidiary’s ability to obtain funds from Summit LLC or its direct or indirect subsidiaries.

The following condensed consolidating balance sheets, statements of operations and cash flows are provided for the Issuers, the Wholly-owned Guarantors and the Non-Guarantors. On March 17, 2015, the noncontrolling interests of Continental Cement were purchased resulting in Continental Cement being a wholly-owned indirect subsidiary of Summit LLC. Continental Cement’s results of operations and cash flows are reflected with the Guarantors for the three and six months ended June 27, 2015. In 2014, Continental Cement’s results are shown separately as a Non Wholly-owned Guarantor.

Earnings from subsidiaries are included in other income in the condensed consolidated statements of operations below. The financial information may not necessarily be indicative of the financial position, results of operations or cash flows had the guarantor or non-guarantor subsidiaries operated as independent entities.

14. SUBSEQUENT EVENTS

On August 5, 2015, Summit Inc. priced the offering of 19,500,000 shares of its Class A common stock at a price to the public of $25.75 per share. The underwriters have been granted a 30-day option to purchase up to an additional 2,925,000 shares of Class A common stock. The offering is expected to close on August 11, 2015, subject to customary closing conditions. Summit Inc. intends to use all of the net proceeds from the offering to purchase for cash 3,750,000 newly-issued LP Units from Summit Holdings and 15,750,000 outstanding LP Units from certain pre-IPO owners, including affiliates of the Sponsors and certain of the Company’s directors and officers. Summit Holdings intends to use the proceeds it receives to pay all or a portion of the $80.0 million deferred purchase price of the Davenport Assets and for general purposes.

On July 17, 2015, the Company acquired certain assets of Lafarge, including a cement plant, a quarry and seven cement distribution terminals for a purchase price of $450.0 million cash and a cement distribution terminal in Bettendorf, Iowa. Due to the recent nature of the acquisition, it is impracticable to include a schedule of the fair value of the assets acquired and liabilities assumed as of the acquisition date and the Davenport Assets’ interim results of operations for the three and six months ended June 30, 2015.

On July 8, 2015, the Issuers issued $350.0 million in aggregate principal amount of 6.125% senior notes due July 15, 2023 (the “2023 Notes”). The 2023 Notes were issued at 100% of their par value. Interest on the 2023 Notes is payable semi-annually on January 15 and July 15 of each year commencing on January 15, 2016. On July 17, 2015, the Company refinanced its term loan under the Senior Secured Credit Facilities (the “Refinancing”). The Refinancing, among other things: (i) reduced the applicable margins used to calculate interest rates for term loans under our Senior Secured Credit Facilities to 3.25% for LIBOR rate loans and 2.25% for base rate loans, subject to a LIBOR floor of 1.00% (and one 25 basis point step down upon Summit LLC achieving a certain first lien net leverage ratio); (ii) increased term loans borrowed under our term loan facility to an aggregate $650.0 million; and (iii) created additional flexibility under the financial maintenance covenants, which are tested quarterly, by increasing the applicable maximum Consolidated First Lien Net Leverage Ratio (as defined in the Credit Agreement).

The Company used the net proceeds from the 2023 Notes and the Refinancing to finance an initial $370.0 million cash purchase price for the Davenport Assets, to refinance its existing senior secured term loan facility, to redeem $183.0 million aggregate principal amount of its outstanding 2020 Notes and to pay related fees and expenses. The remaining $80.0 million of the purchase price for the Davenport Assets is due to Lafarge no later than December 31, 2015 and accrues interest at an annual rate of 7.5%, payable monthly.
