Words such as “outlook,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “should,” “could,” “project,” and similar expressions, as well as statements in future tense, identify forward-looking statements. You should not consider forward-looking statements as a guarantee of future performance or results. 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, assumptions, uncertainties, and risks that could cause such differences are discussed in the Company’s Transition Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 2, 2018 and other filings with the SEC. The forward-looking statements in this presentation are expressly qualified in their entirety by this cautionary statement. The Company undertakes no obligation to update these forward-looking statements to reflect new information, or events or circumstances arising after such date. This presentation includes certain “Non-GAAP” financial measures as defined by Regulation G of the SEC. As required by the SEC, a reconciliation of those measures to the most directly comparable GAAP measures is provided on the Regulation G slides included as slides 13 through 21 of this presentation. Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the Company’s reported GAAP results. 2

These estimates are based on contract terms and evaluations regarding the timing of the services to be provided. In the case of master service agreements, backlog is estimated 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 comprises 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. 7

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 comparable prior 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 periods. 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 the non-cash amortization of the debt discount and the related tax impact 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 Company’s 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 from Tax Reform - During the quarter ended January 27, 2018, the Company recognized an income tax benefit of approximately $32.2 million resulting from tax reform, primarily due to a reduction of net deferred tax liabilities. The Company has excluded this impact because it is a significant change in the U.S. federal corporate tax rate and because the Company believes it is not indicative of the Company’s underlying results or ongoing operations. • Tax impact of excess tax benefits as a result of ASU 2016-09 - ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”) became effective for the Company July 30, 2017, the first day of the 2018 transition period, and changed the treatment of windfalls (or shortfalls) arising from the vesting and exercise of share-based awards. Prior to ASU 2016-09, these amounts were recorded as an adjustment to additional paid-in capital. With the adoption of ASU 2016-09, these amounts are now captured in the Company’s provision for income taxes. The Company excluded the impact of approximately $6.9 million of excess tax benefits during the quarter ended January 27, 2018 from its provision for income taxes in its Non-GAAP measures as this amount may vary significantly from period to period and excluding this amount from the Company’s Non-GAAP financial measures provides management with a more 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. 13

(b) Non-GAAP Adjusted Interest Expense excludes the non-cash amortization of the debt discount associated with the Notes. (c) For both the Trailing 4 Quarters Ended January 27, 2018 and the quarter ended January 27, 2018, Adjusted Non-GAAP provision for income taxes excludes: (i) an income tax benefit of $32.2 million resulting from tax reform, primarily due to the re-measurement of the Company's net deferred tax liabilities at a lower U.S. federal corporate income tax rate; (ii) an income tax benefit of $6.9 million from the vesting and exercise of share-based awards in accordance with ASU 2016-09, Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"); and (iii) the tax related impact of the debt discount associated with the Notes (see footnote (b) above). (d) Shares used in computing Diluted earnings per share for the Trailing 4 Quarters Ended January 27, 2018 is equal to the average diluted shares outstanding in the four trailing quarters. For the quarter ended January 27, 2018, diluted shares used in computing expected GAAP Diluted Earnings per Common Share includes approximately 0.4 million common shares from the dilutive effect of the Notes based on the average share price during the quarter ended January 27, 2018. The Company has a note hedge in effect to offset the economic dilution of additional shares from the Notes up to an average quarterly share price of $130.43 per share. Non-GAAP Adjusted Diluted Shares excludes the GAAP dilutive effect of the Notes based on the expected effect of the note hedge. See the Company's Form 8-K previously filed with the Securities and Exchange Commission on September 28, 2015 for further information regarding the Notes and note hedge.

Appendix: Regulation G Disclosure Reconciliation of Non-GAAP Financial Measures to Comparable GAAP Financial Measures Outlook – Non-GAAP Diluted Earnings per Common Share Unaudited Quarter Ending October 27, 2018 Fiscal 2019 (a) (Q3-19) (a) Diluted earnings per common share – GAAP $2.17 - $2.62 $0.69 - $0.93 Adjustment for addback of after-tax non-cash amortization of debt discount and dilutive share effect of Notes (b)(c) 0.45 0.11 Non-GAAP Adjusted Diluted Earnings per Common Share $2.62 - $3.07 $0.80 - $1.04 Diluted shares (in millions) (c) 32.0 31.8 Adjustment for economic benefit of note hedge related to Notes (in millions) (c) (0.2) - Non-GAAP Adjusted Diluted Shares (in millions) (c) 31.8 31.8 (a) The tax effects of future vestings and exercises of share-based awards are excluded from both Diluted earnings per common share - GAAP and Non-GAAP Adjusted Diluted Earnings per Common Share. (b) The Company expects to recognize approximately $19.1 million and $4.8 million in pre-tax interest expense during fiscal 2019 and the quarter ending October 27, 2018, respectively, for the non-cash amortization of the debt discount associated with the Notes. The addback for fiscal 2019 also includes approximately $0.01 per share for the Non-GAAP impact of the dilutive share effect of the Notes. (c) Actual GAAP diluted shares will include any applicable dilutive effect of the Notes based on the average share price during the respective period. The Company has a note hedge in effect to offset the economic dilution of additional shares from the Notes up to an average quarterly price of $130.43 per share. Accordingly, for Non-GAAP Adjusted Diluted Earnings per Common Share calculations, the Company expects to present results per share that exclude the dilutive share effect of the Notes, if any, based on the expected effect of the note hedge.
