Summit Materials Announces Second Quarter 2015 Results

Denver, Colorado (August 3, 2015) — Summit Materials, Inc. (NYSE: SUM, “Summit” or the “Company”), a leading vertically integrated construction materials company, today announced results for the second quarter ended June 27, 2015.

Second Quarter 2015 Highlights Compared to Second Quarter 2014:

• Net revenue increased 12.5% to $329.0 million.

• Net income approximately break even, compared to $14.2 million

• Further Adjusted EBITDA grew 28.4% to $78.1 million.

• Operating income improved 24.7% to $42.3 million.

• Gross profit increased 25.1% to $115.8 million.

• Aggregates, cement, ready-mixed concrete and asphalt volumes grew 33.1%, 0.7%, 17.5% and 7.0%, respectively.

• Aggregates, cement, ready-mixed concrete and asphalt organic price improved 5.1%, 9.1%, 4.8% and 4.6%, respectively.

• In June 2015, acquired Lewis & Lewis, Inc., a vertically integrated aggregates-based company serving the southwest Wyoming market.

• Redeemed $471.2 million aggregate principal amount of outstanding 10 ¹⁄₂% Senior Notes due 2020 during the second and third quarters of 2015.

Recent Developments:

• In July 2015, Summit completed its previously announced acquisition of a 1.2 million short ton capacity cement plant in Davenport, Iowa along with seven cement distribution terminals (collectively, the “Davenport Assets”) from Lafarge North America Inc. (“Lafarge”) for a purchase price of $450.0 million in cash, plus an exchange of Summit’s Bettendorf, Iowa cement distribution terminal. Following completion of the transaction, Summit owns 2.4 million short tons of cement production capacity across the two cement plants plus eight cement distribution terminals along the Mississippi River system.

• Summit completed an offering of $350 million aggregate principal amount of 6.125% Senior Notes due 2023 and also entered into a new $650 million term loan facility due 2022, which replaced Summit’s prior $422 million term loan due 2019.

Tom Hill, the President and CEO of Summit, stated, “During the second quarter we produced significant growth in net revenues and margins across all of our lines of business. This strong improvement reflects the steady demand improvement in all of our regions, despite some weather-related challenges, mainly in Texas and Kansas, and our disciplined focus on price optimization across our vertically integrated lines of businesses. We achieved this while also expanding our Further Adjusted EBITDA margin by 300 basis points and generating incremental margins in excess of 50%. The success of our acquisition strategy was also evident in our results with more than half of our profit growth contributed by our accretive acquisitions, including the recent strategic bolt on addition of Lewis & Lewis, a vertically integrated aggregates-based business, in our West region.”

Mr. Hill continued, “We believe our sustained progress is a direct result of the steps we have taken to expand our business into attractive markets and establish leadership positions throughout our diversified footprint. Our completion of the Davenport Assets acquisition was an exciting milestone for our company and significantly advanced our position as a leading cement producer in the Midwest. We are now better positioned to continue enhancing our materials earnings exposure and overall profitability as we integrate these assets onto our platform. As we look to the back half of 2015, we plan to capitalize on the improving demand environment to improve our profitability while also remaining opportunistic with our capital to further expand our businesses in select target markets.”

Second Quarter 2015 Operating Results

In the second quarter 2015, net revenue increased 12.5% to $329.0 million, compared to $292.4 million in the prior year quarter. The increase in net revenue was primarily attributable to an increase in volumes across all lines of business, led by the West and Central regions. Net revenue grew organically by $9.3 million, or 3.2%, compared to the prior year quarter.

Further Adjusted EBITDA increased 28.4% to $78.1 million, compared to $60.9 million in the prior year quarter, with growth in all regions. As a percentage of net revenue, Further Adjusted EBITDA improved to 23.8%, compared to 20.8% in the prior year quarter. Adjusted EBITDA by region in the second quarter 2015 compared to the prior year quarter was as follows:

• The West Region grew $8.7 million, or 28.4%, primarily driven by a higher mix of net revenue from aggregates, organic volume and price growth and the impact of acquisitions, mainly in the Houston and Midland/Odessa, Texas and British Columbia, Canada markets.

• The Central Region increased $6.7 million, or 23.2%, largely attributable to price growth across all lines of business, stronger volume in aggregates and ready-mixed concrete and the favorable impact of acquisition activity.

• The East Region improved $1.6 million, or 20.8%, primarily as a result of higher volume in aggregates leading to a larger mix of net revenue derived from materials.

Gross profit increased 25.1% to $115.8 million, compared to $92.5 million in the prior year quarter. As a percentage of net revenue, gross profit improved to 35.2%, compared to 31.6% in the prior year quarter, primarily attributable to a higher mix of net revenue from materials and products as a result of organic improvement and acquisition activity.

Materials Results – Net revenue from materials increased 29.6% to $88.1 million, compared to $67.9 million in the prior year quarter. Aggregates volumes grew 33.1% driven by 3.5% organic volume growth and the remainder attributable to acquisitions. Aggregates organic price increased 5.1% with the improvement due to higher prices across most markets. Including acquisitions, aggregates price increased 0.3% primarily due to the regional mix effect of acquisitions in markets with lower absolute prices, which partially offset organic price growth. Cement volume and price increased 0.7% and 9.1%, respectively, both driven by additional market demand. Gross profit from materials grew 34.7% to $52.7 million, compared to $39.1 million in the prior year quarter.

Products Results – Net revenue from products increased 12.9% to $173.2 million, compared to $153.4 million in the prior year quarter. Ready-mixed concrete volumes increased 17.5% primarily attributable to acquisitions. Ready-mixed concrete price increased 6.4%, largely benefitting from the pass through of higher cement industry prices. Asphalt volume and price increased 7.0% and 4.8% respectively, mostly reflecting stronger market demand. Gross profit from products increased 40.1% to $44.9 million, compared to $32.1 million in the prior year quarter.

Liquidity and Capital Resources

In April 2015, in connection with its initial public offering in March 2015, the Company redeemed $288.2 million aggregate principal amount of its outstanding 10 ¹⁄₂% Senior Notes due 2020 at a redemption price equal to par, plus an applicable premium of $38.2 million and $5.2 million of accrued and unpaid interest.

At June 27, 2015, the Company had cash of $12.6 million and total outstanding debt of $827.2 million, as compared to cash of $13.2 million and total outstanding debt of approximately $1,064.9 million at December 27, 2014. As of June 27, 2015, the Company’s borrowing capacity was $144.8 million on its $235.0 million revolving credit facility, excluding $24.2 million of letters of credit.

Subsequent Events

On July 17, 2015, Summit completed the acquisition of the Davenports Assets, including a 1.2 million short ton cement plant, a quarry and seven cement distribution terminals, from Lafarge for a purchase price of $450.0 million in cash and a cement distribution terminal in Bettendorf, Iowa. The Davenport Assets are being integrated with and will operate as Continental Cement Company, an existing wholly-owned subsidiary of Summit.

In connection with the acquisition, on July 8, 2015, the Company issued $350.0 million in aggregate principal amount of 6.125% Senior Notes due 2023 at 100.0% of their par value. Additionally, on July 17, 2015, the Company refinanced its term loan under its senior secured credit facilities, in which the Company entered into a new $650 million term loan facility due 2022, replacing the prior $422 million term loan due 2019. The refinancing also reduced the applicable margins used to calculate interest rates for term loans under the Company’s senior secured credit facilities to 3.25% from 3.50%.

The Company used the combined net proceeds from the issuance of the senior notes and the refinancing of the term loan 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 10 ¹⁄₂% Senior Notes due 2020 and to pay related fees and expenses. The remaining $80.0 million of the purchase price for the Davenport Assets is due by December 31, 2015 and accrues interest at an annual rate of 7.5%, payable monthly.

Non-GAAP Financial Measures

The rules of the SEC regulate the use in filings with the SEC of “non-GAAP financial measures,” such as Adjusted EBITDA, Further Adjusted EBITDA, gross profit, adjusted net loss per share, and free cash flow which are derived on the basis of methodologies other than in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). We have provided Adjusted EBITDA, Further Adjusted EBITDA, gross profit, adjusted net loss per share, and free cash flow because, among other things, we believe that they provide investors with additional information to measure our performance, evaluate our ability to service our debt and evaluate certain flexibility under our restrictive covenants. Further Adjusted EBITDA is defined in our senior secured credit facilities and used to measure compliance with covenants, including interest coverage and debt incurrence, and is used to measure our debt incurrence and restricted payment capacity under the indenture governing our senior notes. Our use of the terms Adjusted EBITDA, Further Adjusted EBITDA, gross profit and adjusted net loss per share, may vary from the use of such terms by others and should not be considered as alternatives to net income (loss), operating income (loss), revenue or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance or to cash flows as measures of liquidity.

Adjusted EBITDA and Further Adjusted EBITDA and other non-GAAP measures have important limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP. Some of the limitations of Adjusted EBITDA and Further Adjusted EBITDA are that these measures do not reflect: (i) our cash expenditures or future requirements for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, our working capital needs; (iii) interest expense or cash requirements necessary to service interest and principal payments on our debt; (iv) income tax payments we are required to make; and (v) any cash requirements for the replacement cost of assets being depreciated or amortized. Because of these limitations, we rely primarily on our U.S. GAAP results and use Adjusted EBITDA and Further Adjusted EBITDA only supplementally.

Adjusted EBITDA, Further Adjusted EBITDA, gross profit, adjusted net loss per share, and free cash flow reflect an additional way of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliations to U.S. GAAP financial measures included in the tables attached to this press release, may provide a more complete understanding of factors and trends affecting our business. However, non-GAAP financial measures should not be construed as being more important than other comparable U.S. GAAP financial measures and should 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 financial statements in their entirety and not rely on any single financial measure.

Reconciliations of the non-GAAP measures used in this press release are included in the tables attached to this press release.

Cautionary Statement Regarding Forward-Looking Statements

This press release contains “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. Any and all statements made relating to the timing, funding of, and expectations for our anticipated purchase of the Davenport Assets, the macroeconomic outlook for our markets, potential acquisition activity, our estimated and projected earnings, margins, costs, expenditures, cash flows, sales volumes and financial results are forward-looking statements. These forward-looking statements are subject to risks and uncertainties that may change at any time, and, therefore, our actual results may differ materially from those expected. 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 impact 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 achieved. 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 our prospectus dated March 11, 2015, filed with the SEC on March 13, 2015. Such factors may be updated from time to time in our periodic filings with the SEC, which are accessible on the SEC’s website at www.sec.gov.

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 otherwise required by law.
