Non-GAAP Reconciliations

23 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 entirety of both the current and prior year periods, excluding contract revenues from certain non-recurring items. 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. For comparability to other companies in the industry, the Company includes storm restoration revenues from businesses that are included for the entirety of both the current and prior year periods in its Non-GAAP Organic Contract Revenues beginning with the results reported for the fourth quarter and fiscal year ended January 25, 2025. • Non-GAAP Adjusted EBITDA – EBITDA (earnings before interest, taxes, depreciation and amortization) adjusted for 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 certain non-recurring items and the related tax impact. 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. • Notional Net Debt - aggregate face amount of outstanding debt less cash and equivalents. Management believes notional net debt is a helpful measure to assess the Company’s liquidity. Management excludes or adjusts each of the items identified below from Non-GAAP Adjusted EBITDA, Non-GAAP Adjusted Net Income and Non-GAAP Adjusted Diluted Earnings per Common Share: • Stock-based compensation modification - During the quarter ended July 27, 2024, the Company announced its CEO succession plan and transition. In connection with this transition, the Company incurred stock-based compensation modification expense. The Company excludes the impact of the award modification because the Company believes it is not indicative of its underlying results or ongoing operations. • Loss on debt extinguishment - Loss on debt extinguishment includes the write-off of deferred financing fees in connection with the amendment of the Company’s credit agreement during the quarter ended July 27, 2024. Management believes excluding the loss 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. • Acquisition integration costs – The Company incurred costs of approximately $4.2 million in connection with the integration of a business acquired during the quarter ended October 26, 2024. The exclusion of the acquisition integration costs from the Company’s Non-GAAP financial measures provides management with a consistent measure for assessing financial results. • 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.

31 1. The Company’s backlog represents an estimate of services to be performed pursuant to master service agreements and other contractual agreements over the terms of those contracts. 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 12-month period, when available. When estimating backlog for newly initiated master service agreements and other long and short-term contracts, the Company also considers the anticipated scope of the contract and information received from the customer during the procurement process. A significant majority of the Company’s 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 (“GAAP”) and should be considered in addition to, but not as a substitute for, information provided in accordance with GAAP. Participants in the Company’s industry also disclose a calculation of their backlog; however, the Company’s methodology for determining backlog may not be comparable to the methodologies used by others. Dycom utilizes the calculation of backlog to assist in measuring aggregate awards under existing contractual relationships with its customers. The Company believes its backlog disclosures will assist investors in better understanding this estimate of the services to be performed pursuant to awards by its customers under existing contractual relationships. 2. Non-GAAP Organic Contract Revenues are contract revenues from businesses that are included for the entirety of both the current and prior year periods, excluding contract revenues from certain nonrecurring items. 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. For comparability to other companies in the industry, the Company includes storm restoration revenues from businesses that are included for the entirety of both the current and prior year periods in its Non-GAAP Organic Contract Revenues beginning with the results reported for the fourth quarter and fiscal year ended January 25, 2025. 3. The impacts of a change order and the closeout of several projects increased contract revenues by $26.5 million for the quarter ended October 28, 2023 and fiscal year ended January 27, 2024. After the impacts of certain other costs, these items contributed $23.6 million to Adjusted EBITDA for the quarter ended October 28, 2023 and fiscal year ended January 27, 2024. As a result, reported Adjusted EBITDA was increased by 1.8% and 0.6% as a percentage of contract revenues for the quarter ended October 28, 2023 and fiscal year ended January 27, 2024, respectively. On an after-tax basis, these items contributed approximately $17.5 million to reported net income, or $0.59 per common share diluted for the quarter ended October 28, 2023 and fiscal year ended January 27, 2024. Non-GAAP Organic Revenue Growth %, Non-GAAP Adjusted EBITDA, Non-GAAP Adjusted EBITDA %, Non-GAAP Adjusted Net Income and Non-GAAP Adjusted Diluted Earnings per Common Share exclude the impact of these items for the quarter ended October 28, 2023 and fiscal year ended January 27, 2024. 4. During Q3 2025 revenues from storm restoration services were $46.3 million, of which $25.2 million were from acquired businesses and $21.1 million was from businesses that were owned for the entirety of both the current and prior year periods. Non-GAAP Organic Revenue growth was 9.6% including the $21.1 million from businesses that were owned for the entirety of both the current and prior year periods compared to 7.6% when total storm restoration services of $46.3 million are excluded from the calculation. Total revenues from acquired businesses were $105.3 million including the $25.2 million of storm restoration services. During fiscal 2022 revenues from storm restoration services were $3.9 million. Non-GAAP Organic Revenue growth for fiscal 2023 was 21.7% when including the fiscal 2022 storm restoration services in the calculation compared to 21.8% when total storm restoration services are excluded from the calculation. 5. As of both Q1 2026 and Q4 2025, the Company had $47.5 million of standby letters of credit outstanding under the Senior Credit Facility. 6. Liquidity represents the sum of availability from the Company’s Senior Credit Facility, considering net funded debt balances, and available cash and equivalents. For calculation of availability under the Senior Credit Facility, applicable cash and equivalents are netted against the funded debt amount. 7. DSO is calculated as the summation of current and non-current accounts receivable (including unbilled receivables), net of allowance for doubtful accounts, plus current contract assets, less contract liabilities, divided by average revenue per day during the respective quarter. Long-term contract assets are excluded from the calculation of DSO, as these amounts represent payments made to customers pursuant to long-term agreements and are recognized as a reduction of contract revenues over the period for which the related services are provided to the customers. 8. The Company recognized a loss on debt extinguishment of approximately $1.0 million in connection with the amendment of its credit agreement during the quarter ended July 27, 2024. 9.
