RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

TO COMPARABLE GAAP FINANCIAL MEASURES (CONTINUED)

Explanation of Non-GAAP Financial 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 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 change percentage is calculated as the change in Non-GAAP Organic Contract Revenues from the comparable prior year period divided by the comparable prior year period Non-GAAP Organic Contract Revenues. Management believes Non-GAAP Organic Contract Revenues 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, certain tax impacts resulting from vesting and exercise of share-based awards, and certain non-recurring items. Management believes Non-GAAP Adjusted Net Income is a helpful measure for comparing the Company’s operating performance with prior periods.

•Non-GAAP Adjusted Diluted Earnings per Common Share - Non-GAAP Adjusted Net Income divided by weighted average diluted shares outstanding.

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 debt discount on 2021 Convertible Notes - The Company’s 2021 Convertible Notes were allocated between debt and equity components. The difference between the principal amount and the carrying amount of the liability component of the 2021 Convertible Notes represents a debt discount. The debt discount is being amortized over the term of the 2021 Convertible Notes but does not result in periodic cash interest payments. The Company excludes 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 2021 Convertible 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.

•Goodwill impairment charge - During the six months ended July 25, 2020, the Company incurred a goodwill impairment charge of $53.3 million for a reporting unit that performs installation services inside third party premises. Management believes excluding the goodwill impairment charge from the Company’s Non-GAAP financial measures assists investors’ overall understanding of the Company’s current financial performance and provides management with a consistent measure for assessing the current and historical financial results.

•Loss (gain) on debt extinguishment - During the six months ended July 31, 2021, the Company recognized a loss on debt extinguishment of $0.1 million in connection with the amendment and restatement of its credit agreement maturing in April 2026. During the six months ended July 25, 2020, the Company recognized a gain on debt extinguishment of $12.0 million in connection with its purchase of $401.7 million aggregate principal amount of the Company’s 2021 Convertible Notes for $371.4 million, including interest and fees. Management believes excluding the loss (gain) on debt extinguishment from the Company’s Non-GAAP financial measures assists investors’ overall understanding of the Company’s current financial performance and provides management with a consistent measure for assessing the current and historical financial results.

7

•Tax impact of the vesting and exercise of share-based awards - The Company excludes certain tax impacts resulting from the vesting and exercise of share-based awards as these amounts may vary significantly from period to period. Excluding these amounts from the Company’s Non-GAAP financial measures provides management with a more consistent measure for assessing financial results.

•Tax effect from a net operating loss carryback under enacted CARES Act - During the six months ended July 25, 2020, the Company recognized an income tax benefit of $2.6 million from a net operating loss carryback under the enacted U.S. Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The Company excludes this impact because the Company believes it is not indicative of the Company’s underlying results or ongoing operations.

•Tax impact of pre-tax adjustments - The tax impact of pre-tax adjustments reflects the Company’s estimated tax impact of specific adjustments and the effective tax rate used for financial planning for the applicable period.
