Announces 2013 Fourth Quarter and Full Year Results

DENVER, Colorado (March 7, 2014) - Summit Materials, LLC today announced results for the quarter and year ended December 28, 2013.

• Revenue increased 2.9% to $238.3 million.

• Aggregate and ready-mixed concrete volumes increased 14% and 28%, respectively. Cement and asphalt volumes decreased 28% and 9%, respectively.

Notable items for the year (all comparisons are with 2012):

• Product revenue increased $4.8 million; total revenue was slightly down by 1.1%.

• Aggregate and ready-mixed concrete volumes increased 5% and 9%, respectively, while cement and asphalt volumes declined 4% and 14%, respectively.

• Pricing increased for each of our product lines.

• $68.2 million of goodwill impairment charges recognized. Excluding the goodwill impairment charge, operating earnings improved $4.8 million.

2013 Financial Results Compared to 2012

Tom Hill, the CEO of Summit Materials, stated, “This year we were pleased with our performance. A safety-first culture helped us improve in each of our key safety metrics. We were able to achieve a slight improvement in product revenue of $4.8 million, or 0.8%, compared to last year. Excluding the fourth quarter goodwill impairment charges of $68.2 million, our operating earnings improved by $4.8 million. Adjusted EBITDA increased by $16.4 million from 2012. Our product pricing increased in many of our markets in Texas, Missouri, Kentucky and Kansas. As a result of our focus on lower-volume, higher-margin contracts, disciplined integration of strategic acquisitions in Kansas and Utah and a continued focus on costs, we enjoyed improved margins from 2012. Weather conditions in the first half of 2013 were not favorable; however, we have a strong backlog going into 2014, with our aggregates backlog 33% higher than at this point last year. In addition, we increased our footprint in Texas with our January acquisition of Alleyton Resources, an aggregates and ready-mixed concrete business in Houston that we believe is well-positioned to serve that growing market.”

Central Region Results

The Central Region’s revenue increased 9.1% due to higher aggregate, asphalt and ready-mixed concrete volumes and pricing improvements in aggregates, ready-mixed concrete and cement. Adjusted EBITDA improved by $7.2 million due to the revenue growth and reduced stripping costs.

West Region Results

The West Region’s revenue declined 12.1% due to a shift to lower-volume, higher-margin projects and a reduction in grading and structural projects. Despite the reduction in sales, Adjusted EBITDA in the West Region increased $14.2 million. This was primarily driven by improved margins on aggregates, asphalt and ready-mixed concrete and improved performance in the Texas construction services business.

1

East Region Results

The East Region’s revenue increased $21.2 million, while Adjusted EBITDA increased $4.4 million. This region saw growth in aggregate and asphalt volumes. The increase in Adjusted EBITDA was driven by increased aggregate pricing and various cost savings initiatives.

Liquidity and Capital Resources

Our primary sources of liquidity include cash on-hand, cash provided by our operations and amounts available for borrowing under our credit facilities. As of December 28, 2013, we had $14.9 million in cash and working capital of $85.4 million as compared to cash and working capital of $27.4 million and $114.4 million at December 29, 2012, respectively. We calculate working capital as current assets less current liabilities, excluding the current portion of long term debt and outstanding borrowings on our revolver facility. As of December 28, 2013, our remaining borrowing capacity on our senior secured revolving credit facility was $105.7 million, net of $18.3 million of outstanding letters of credit.

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 we wind down the construction season and enter the winter months, which is when we see significant inflows of cash from the collection of receivables.

Free cash outflow utilization, a non-GAAP measure defined as operating cash outflow less net capital expenditures, was $16.5 million and $25.6 million in the years ended December 28, 2013 and December 29, 2012, respectively. Free cash outflow in 2013, as compared to 2012, was affected by increased investment of $13.3 million in capital projects. In 2013, we continued development of an underground mine and built a storage dome for our cement business based in Hannibal, Missouri and installed a new hot mix asphalt plant on-line in Austin, Texas.

Our growth strategy considers future acquisitions for which we believe we have access to sufficient capital through committed funds from our sponsors, Blackstone Capital Partners V L.P. and Silverhawk Summit, L.P., and our borrowing capacity.

On January 17, 2014, we issued $260.0 million of 10.5% senior notes due 2020. Proceeds from the notes were used to acquire Alleyton Resources, pay down outstanding borrowings on our senior secured revolving credit facility and for general corporate purposes.

Non-GAAP Financial Measures

We have included certain non-GAAP financial measures in this release including Adjusted EBITDA and Pro Forma Adjusted EBITDA, because 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. Our senior secured credit facilities use Pro Forma Adjusted EBITDA to measure compliance with covenants such as interest coverage and debt incurrence and the indenture governing our senior notes uses Adjusted EBITDA in connection with our debt incurrence and restricted payment capacity. Our chief operating decision maker also considers our free cash flow as a measure of operating performance. We define free cash flow as net cash provided by (used for) operating activities less purchases of property, plant and equipment. Our use of the terms Adjusted EBITDA, Pro Forma Adjusted EBITDA and free cash flow may vary from the use of such terms by others in our industry and should not be considered as alternatives to net loss, operating (loss) income, revenue or any other performance measures derived in accordance with GAAP as measures of operating performance or to cash flows as measures of liquidity.

Adjusted EBITDA, Pro Forma Adjusted EBITDA and free cash flow 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 GAAP. Some of the limitations of Adjusted EBITDA, Pro Forma Adjusted EBITDA and free cash flow are that these measures do not reflect: (i) changes in, or cash requirements for, our working capital needs; (ii) the significant interest expense or cash requirements necessary to service interest and principal payments on our debt; and (iii) any cash requirements for the replacement cost of assets being depreciated or amortized. Because of these limitations, we rely primarily on our GAAP results and use Adjusted EBITDA, Pro Forma Adjusted EBITDA and free cash flow only supplementally.

Adjusted EBITDA, Pro Forma Adjusted EBITDA 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 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 GAAP financial measures and must be considered in conjunction with the 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 Adjusted EBITDA and Pro Forma Adjusted EBITDA to net income (loss) and from free cash flow to cash flows from operations 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,” “plans,” “estimates,” “projects” or “anticipates” or similar expressions that concern our strategy, plans or intentions.

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.

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.

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.
