Use of Non-GAAP Financial Measures

"Net Revenue," defined as contract revenue as reported in accordance with U.S. generally accepted accounting principles ("GAAP") minus subcontractor services and other direct costs, is a non-GAAP financial measure. Net Revenue is a supplemental measure that Willdan believes enhances investors’ ability to analyze Willdan’s business trends and performance because it substantially measures the work performed by Willdan’s employees. In the course of providing services, Willdan routinely subcontracts various services. Generally, these subcontractor services and other direct costs are passed through to Willdan’s clients and, in accordance with GAAP and industry practice, are included in Willdan’s revenue when it is Willdan’s contractual responsibility to procure or manage such subcontracted activities. Because subcontractor services and other direct costs can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of Willdan’s business trends. Accordingly, Willdan segregates subcontractor services and other direct costs from revenue to promote a better understanding of Willdan’s business by evaluating revenue exclusive of subcontract services and other direct costs associated with external service providers. A reconciliation of Willdan’s contract revenue as reported in accordance with GAAP to Net Revenue is provided at the end of this press release. A reconciliation of targeted contract revenue for fiscal year 2026 as reported in accordance with GAAP to targeted Net Revenues for fiscal year 2026, which is a forward-looking non-GAAP financial measure, is not provided because Willdan is unable to provide such reconciliation without unreasonable effort. The inability to provide a reconciliation is due to the uncertainty and inherent difficulty of predicting the subcontractor services and other director costs that are subtracted from contract revenues in order to derive Net Revenues. While subcontractor costs have increased recently, subcontractor costs can vary significantly from period to period. Subcontractor costs and other direct costs were 45.7% and 44.7% of contract revenue for the six months ended July 3, 2026 and July 4, 2025, respectively, and 46.5% of contract revenue for the fiscal year 2025.

"Adjusted EBITDA," defined as net income plus interest expense, income tax expense, stock-based compensation, interest accretion, depreciation and amortization, transaction costs, and gain on sale of equipment, is a non-GAAP financial measure. Adjusted EBITDA is a supplemental measure used by Willdan’s management to measure Willdan’s operating performance. Willdan believes Adjusted EBITDA is useful because it allows Willdan’s management to evaluate its operating performance and compare the results of its operations from period to period and against its peers without regard to its financing methods, capital structure and non-operating expenses. Willdan uses Adjusted EBITDA to evaluate its performance for, among other things, budgeting, forecasting and incentive compensation purposes.

Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s costs of capital and stock-based compensation, as well as the historical costs of depreciable assets. A reconciliation of net income as reported in accordance with GAAP to Adjusted EBITDA is provided at the end of this press release. A reconciliation of targeted net income for fiscal year 2026 as reported in accordance with GAAP to Adjusted EBITDA for fiscal year 2026, which is a forward-looking non-GAAP financial measure, is not provided because Willdan is unable to provide such reconciliation without unreasonable effort. The inability to provide a reconciliation is due to the uncertainty and inherent difficulty of predicting the interest expense, income tax expense, stock-based compensation, interest accretion, depreciation and amortization, and gain on sale of equipment that are subtracted from net income in order to derive Adjusted EBITDA.

"Adjusted Net Income," defined as net income plus stock-based compensation, intangible amortization, interest accretion, and transaction costs, each net of tax, is a non-GAAP financial measure.

"Adjusted Diluted EPS," defined as net income plus stock-based compensation, intangible amortization, interest accretion, and transaction costs, each net of tax, all divided by the diluted weighted-average shares outstanding, is a non-GAAP financial measure. Adjusted Net Income and Adjusted Diluted EPS are supplemental measures used by Willdan’s management to measure its operating performance. Willdan believes Adjusted Net Income and Adjusted Diluted EPS are useful because they allow Willdan’s management to more closely evaluate and explain the operating results of Willdan’s business by removing certain non-operating expenses.

Reconciliations of net income as reported in accordance with GAAP to Adjusted Net Income and diluted EPS as reported in accordance with GAAP to Adjusted Diluted EPS are provided at the end of this press release. Reconciliations of targeted net income as reported in accordance with GAAP to targeted Adjusted Net Income for fiscal year 2026, which is a forward-looking non-GAAP financial measure, and targeted diluted EPS as reported in accordance with GAAP to targeted Adjusted Diluted EPS for fiscal year 2026, which is a forward-looking non-GAAP financial measure, are not provided because Willdan is unable to provide such reconciliations without unreasonable effort. The inability to provide such reconciliations is due to the uncertainty and inherent difficulty of predicting the stock-based compensation, intangible amortization, and interest accretion, each net of tax, that are subtracted from net income and diluted EPS in order to derive Adjusted Net Income and Adjusted Diluted EPS, respectively.

Willdan’s definitions of Net Revenue, Adjusted EBITDA, Adjusted Net Income and Adjusted Diluted EPS have limitations as analytical tools and may differ from other companies reporting similarly named measures or from similarly named measures Willdan has reported in prior periods. These measures should be considered in addition to, and not as a substitute for, or superior to, other measures of financial performance prepared in accordance with GAAP, such as contract revenue, net income and diluted EPS.
