Raymond James 34th Annual Institutional Investors Conference March 5, 2013

2 Forward-Looking Statements and Non-GAAP Information Fiscal 2013 second quarter 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. All statements, other than statements of historical facts, 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. Additionally, forward–looking statements may include statements of expectations regarding our recent acquisition of the businesses of the telecommunications infrastructure services subsidiaries of Quanta Services, Inc., including expected benefits and synergies of the transaction, future financial and operating results and future opportunities for the combined businesses, 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 recently completed acquisition. 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 28, 2012, 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 at the end 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.

Currently, we have over 14,700 fiber builds complete across our footprint, and we anticipate completing an additional 4,000 to 5,000 builds in 2013.

(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.

30 Regulation G Disclosure The below table presents the Non-GAAP financial measures of EBITDA and Adjusted EBITDA for the respective periods. EBITDA and Adjusted EBITDA are Non-GAAP financial measures within the meaning of Regulation G promulgated by the Securities and Exchange Commission. The Company defines EBITDA as earnings before interest, taxes, depreciation and amortization, and defines Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, gain on sale of fixed assets, stock-based compensation expense and Adjusting items. The Company believes these Non-GAAP financial measures provide 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 these Non-GAAP financial measures to evaluate its past performance and prospects for future performance. EBITDA and Adjusted EBITDA are not recognized terms under GAAP and do 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. These tables present a reconciliation of EBITDA and Adjusted EBITDA to the most directly comparable GAAP measure.
