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 e
