(a) (a) (a) (a) (a) Due to the change in the Company’s fiscal year end, the Company’s fiscal 2018 six month transition period consisted of Q1-18 and Q2-18. Selected Current Awards and Extensions Approximate Customers Description Area Term (in years) Comcast Framework Agreement Multi-year Verizon Construction & Engineering Services Various 4 AT&T Construction Services Michigan, Indiana, Ohio 3 Windstream Construction Services Pennsylvania 3 Various Rural and Other Services Oregon, South Dakota, Indiana, Virginia, South Carolina 1-2 Notes: Our backlog estimates represent amounts under master service agreements and other contractual agreements for services projected to be performed over the terms of contracts. These estimates are generally based on contract terms and assessments regarding the timing of the services to be provided. In the case of master service agreements, backlog is calculated based on the work performed in the preceding twelve month period, when available. When estimating backlog for newly initiated master service agreements and other long and short term contracts, we also consider the anticipated scope of the contract and information received from the customer in the procurement process. A significant majority of our backlog estimates comprise services under master service agreements and other long term contracts. Backlog is not a measure defined by United States generally accepted accounting principles; however, it is a common measurement used in our industry. Our methodology for determining backlog may not be comparable to the methodologies used by others. 6

Appendix: Regulation G Disclosure Explanation of Non-GAAP Measures The Company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). In the Company’s quarterly results releases, trend schedules, conference calls, slide presentations, and webcasts, it may use or discuss Non-GAAP financial measures, as defined by Regulation G of the Securities and Exchange Commission. The Company believes that the presentation of certain Non-GAAP financial measures in these materials provides information that is useful to investors because it allows for a more direct comparison of the Company’s performance for the period reported with the Company’s performance in prior periods. The Company cautions that Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the Company’s reported GAAP results. Management defines the Non-GAAP financial measures used in this presentation as follows: • Non-GAAP Organic Contract Revenues - contract revenues from businesses that are included for the entire period in both the current and prior year periods, excluding contract revenues from storm restoration services. Non-GAAP Organic Contract Revenue growth (decline) is calculated as the percentage change in Non-GAAP Organic Contract Revenues over those of the comparable prior year period. Management believes organic growth (decline) is a helpful measure for comparing the Company’s revenue performance with prior periods. • Non-GAAP Adjusted EBITDA - net income before interest, taxes, depreciation and amortization, gain on sale of fixed assets, stock-based compensation expense, and certain non-recurring items. Management believes Non-GAAP Adjusted EBITDA is a helpful measure for comparing the Company’s operating performance with prior periods as well as with the performance of other companies with different capital structures or tax rates. • Non-GAAP Adjusted Net Income - GAAP net income before non-cash amortization of the debt discount and the related tax impact, certain tax impacts resulting from vesting and exercise of share-based awards and certain non-recurring items. • Non-GAAP Adjusted Diluted Earnings per Common Share and Non-GAAP Adjusted Diluted Shares - Non-GAAP Adjusted Net Income divided by Non-GAAP Adjusted Diluted Shares outstanding. The Company has a note hedge in effect to offset the economic dilution of additional shares from the Company’s 0.75% convertible senior notes due September 2021 (the “Notes”) up to an average quarterly share price of $130.43. The measure of Non-GAAP Adjusted Diluted shares used in computing Non- GAAP Adjusted Diluted Earnings per Common Share excludes dilution from the Notes. Management believes that the calculation of Non-GAAP Adjusted Diluted shares to reflect the note hedge will be useful to investors because it provides insight into the offsetting economic effect of the hedge against potential conversion of the Notes. Management excludes or adjusts each of the items identified below from Non-GAAP Adjusted Net Income and Non-GAAP Adjusted Diluted Earnings per Common Share: • Non-cash amortization of the debt discount - The Notes were allocated between debt and equity components. The difference between the principal amount and the carrying amount of the liability component of the Notes represents a debt discount. The debt discount is being amortized over the term of the Notes but does not result in periodic cash interest payments. The Company has excluded the non-cash amortization of the debt discount from its Non-GAAP financial measures because it believes it is useful to analyze the component of interest expense for the Notes that will be paid in cash. The exclusion of the non-cash amortization from the Company’s Non- GAAP financial measures provides management with a consistent measure for assessing financial results. • Tax impact of adjusted results - The tax impact of adjusted results reflects the Company’s effective tax rate used for financial planning for the applicable period. 9
