Investor Presentation June 2014 Exhibit 99.1

2 The three and nine months ended April 26, 2014 results are unaudited. This presentation contains “forward-looking statements” which are statements relating to future events, future financial performance, strategies, expectations, and the competitive environment. Other than statements of historical facts, all statements contained in this presentation, including statements regarding the Company’s future financial position, future revenue, prospects, plans and objectives of management, are forward-looking statements. Forward-looking statements include statements of expectations regarding the businesses acquired during fiscal 2013 (the “acquired subsidiaries”), including expected benefits and synergies of the transaction, future financial and operating results, and other statements regarding events or developments that the Company believes or anticipates will or may occur in the future as a result of the acquisitions. Words such as “outlook,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “forecast,” “may,” “should,” “could,” “project,” “looking ahead” and similar expressions, as well as statements in future tense, identify forward-looking statements. You should not read forward- looking statements as a guarantee of future performance or results. They will not necessarily be accurate indications of whether or at what time such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief at that time with respect to future events. Such statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to factors described under Item 1A, “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended July 27, 2013, and other risks outlined in the Company’s periodic filings with the Securities and Exchange Commission (“SEC”). The forward-looking statements in this presentation are expressly qualified in their entirety by this cautionary statement. Except as required by law, the Company may not update forward-looking statements even though its situation may change in the future. This presentation includes certain “Non-GAAP” financial measures as defined by SEC rules. We believe that the presentation of certain Non-GAAP financial measures provides information that is useful to investors because it allows for a more direct comparison of our performance for the period with our performance in the comparable prior-year periods. As required by the SEC, we have provided a reconciliation of those measures to the most directly comparable GAAP measures on the Regulation G slides included as slides 28 through 32 of this presentation. We caution that Non-GAAP financial measures should be considered in addition to, but not as a substitute for, our reported GAAP results. Forward Looking Statements and Non-GAAP Information

Organic Revenue growth is calculated as the percentage increase in revenues over those of the comparable prior year period (fiscal quarter) for revenues from businesses that are included in both periods for the full fiscal period, excluding revenues from storm restoration services, if any. (b) For comparisons of Organic Revenue beginning with Q3-14, Organic Revenue – Non-GAAP includes revenues of businesses acquired in Q2-13 as the revenues from these businesses are included in both quarters (Q3-14 and Q3-13). (c) Organic revenues from customers for stimulus work comprised of projects funded in part by the American Recovery and Reinvestment Act of 2009. Amounts included for stimulus revenues are organic and, as a result, exclude stimulus work from Acquired Subsidiaries prior to the Q3-14 organic calculation when the Acquired Subsidiaries were in both periods.

30 (a) Organic Revenue – Non-GAAP are revenues from businesses that are included for the full period in both the current and prior year presented, excluding storm restoration services, if any. Organic Revenue growth is calculated as the percentage increase in revenues over those of the comparable prior year period for revenues from businesses that are included in both periods for the full fiscal period, excluding revenues from storm restoration services, if any. (b) Non-GAAP adjustments in FY 2010 reflect adjustments in Q4-10 result from the Company’s 52/53 week fiscal year of $20.1 million. The Q4-10 Non-GAAP adjustments reflect the impact of the additional week in Q4-10 and are calculated by dividing contract revenues by 14 weeks. The result, representing one week of contract revenues, is subtracted from the GAAP-contract revenues to calculate 13 weeks of revenue for Q4-10 on a Non-GAAP basis for comparison purposes. Amounts may not add due to rounding.

31 Appendix: Regulation G Disclosure Selected Information- Reconciliation of GAAP to Non-GAAP Measures ($ in million's, except per share amounts) Amounts may not add due to rounding. The above table presents a reconciliation of the Non-GAAP financial measure of Adjusted EBITDA for the periods specified to the most directly comparable GAAP measure. Adjusted EBITDA is a Non-GAAP financial measure within the meaning of Regulation G promulgated by the Securities and Exchange Commission. The Company defines Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, gain on sale of fixed assets, acquisition related costs, write-off of deferred financing costs, stock-based compensation expense, and certain non-recurring items. The Company believes this Non-GAAP financial measure provides information that is useful to the Company’s investors. The Company believes that this information is helpful in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionate positive or negative impact on the Company’s results of operations in any particular period. Additionally, the Company uses this Non-GAAP financial measure to evaluate its past performance and prospects for future performance. Adjusted EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income, operating cash flows, or a measure of earnings. Because all companies do not use identical calculations, this presentation of Non-GAAP financial measures may not be comparable to other similarly titled measures of other companies.
