CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This Quarterly Report on Form 10-Q (this “10-Q”) contains statements that constitute forward-looking statements as that term is defined by the Private Securities Litigation Reform Act of 1995, as amended. These statements concern our business, operations and financial performance and condition as well as our plans, objectives and expectations for our business operations and financial performance and condition, which are subject to risks and uncertainties. All statements other than statements of historical fact included in this 10-Q are forward-looking statements. These statements may include words such as “aim,” “anticipate,” “assume,” “believe,” “can have,” “could,” “due,” “estimate,” “expect,” “goal,” “intend,” “likely,” “may,” “objective,” “plan,” “potential,” “positioned,” “predict,” “should,” “target,” “will,” “would” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events or trends. For example, all statements we make relating to our plans and objectives for future operations, growth or initiatives and strategies are forward-looking statements.

These forward-looking statements are based on current expectations, estimates, forecasts and projections about our business and the industry in which we operate and our management’s beliefs and assumptions. We derive many of our forward-looking statements from our own operating budgets and forecasts, which are based upon many detailed assumptions. While we believe that our assumptions are reasonable, we caution that predicting the impact of known factors is very difficult, and we cannot anticipate all factors that could affect our actual results.

All of our forward-looking statements are subject to risks and uncertainties that may cause our actual results to differ materially from our expectations. Important factors that could cause actual results to differ materially from our expectations include, but are not limited to:

| ● | our ability to adequately complete projects in a timely manner;

| ● | our ability to compete successfully in the highly competitive energy services market, which represented 84% of our consolidated revenue in fiscal year 2023;

| ● | our reliance on work from our top ten clients, which accounted for 53% of our consolidated contract revenue for fiscal year 2023;

| ● | changes in state, local and regional economies and government budgets;

| ● | our ability to win new contracts, to renew existing contracts and to compete effectively for contracts awarded through bidding processes;

| ● | our ability to make principal and interest payments on our outstanding debt as they come due and to comply with the financial covenants contained in our debt agreements;

| ● | our ability to manage supply chain constraints, labor shortages, rising interest rates, and rising inflation;

| ● | our ability to obtain financing and to refinance our outstanding debt as it matures;

| ● | our ability to successfully integrate our acquisitions and execute on our growth strategy; and

| ● | our ability to attract and retain managerial, technical, and administrative talent.

The above is not a complete list of factors or events that could cause actual results to differ from our expectations, and we cannot predict all of them. All written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by the cautionary statements disclosed elsewhere in this Quarterly Report on Form 10-Q, and under Part I, Item 1A. “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023, as such disclosures may be amended, supplemented or superseded from time to

time by other reports we file with the Securities and Exchange Commission, including subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and public communications. You should evaluate all forward-looking statements made in this Quarterly Report on Form 10-Q and otherwise in the context of these risks and uncertainties.

Potential investors and other readers are urged to consider these factors carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on any forward-looking statements we make. These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are not guarantees of future performance or developments and involve known and unknown risks, uncertainties and other factors that are in many cases beyond our control. Except as required by law, we undertake no obligation to update or revise any forward-looking statements publicly, whether as a result of new information, future developments or otherwise.

1. ORGANIZATION AND OPERATIONS OF THE COMPAN Y

Willdan Group, Inc. (“Willdan” or the “Company”) is a provider of professional, technical and consulting services to utilities, private industry, and public agencies at all levels of government. As resource and infrastructure needs undergo continuous change, the Company helps organizations and their communities evolve and thrive by providing a wide range of technical services for energy solutions, and government infrastructure. Through engineering, program management, policy advisory, and software and data management, the Company designs and delivers trusted, comprehensive, innovative, and proven solutions to improve efficiency, resiliency, and sustainability in energy and infrastructure.

The Company’s broad portfolio of services operates within two financial reporting segments: (1) Energy and (2) Engineering and Consulting. The interfaces and synergies between these segments are important elements of the Company’s strategy to design and deliver trusted, comprehensive, innovative, and proven solutions for its customers.

The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Operations of the Company, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 29, 2023. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements and related notes thereto should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 29, 2023. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.

Fiscal Years

The Company operates and reports its annual financial results based on 52 or 53-week periods ending on the Friday closest to December 31. The Company operates and reports its quarterly financial results based on the 13-week period ending on the Friday closest to June 30, September 30, and December 31 and the 13 or 14-week period ending on the Friday closest to March 31, as applicable. Fiscal year 2024, which ends on December 27, 2024, will be comprised of 52 weeks, with all quarters consisting of 13 weeks each. Fiscal year 2023, which ended on December 29, 2023, was comprised of 52 weeks, with all quarters consisting of 13 weeks each. All references to years in the notes to consolidated financial statements represent fiscal years.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Pronouncements Recently Issued

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 amends the rules on income tax disclosures to require entities to disclose specific categories in the rate reconciliation, the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and income tax expense or benefit from continuing operations (separated by federal, state, and foreign). In addition, ASU 2023-09 requires entities to disclose their income tax payments to international, federal, state, and local jurisdictions, among other changes. The amendments can be applied on a prospective basis although retrospective application is permitted. The amendments are effective for the annual reporting periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact this update will have on its Consolidated Financial Statements.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 expands segment disclosure requirements through enhanced disclosures related to significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The amendments are effective for the fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact this update will have on its Consolidated Financial Statements.

In October 2023, the FASB issued ASU No. 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”). ASU 2023-06 amends U.S. GAAP to reflect updates and simplifications to certain disclosure and presentation requirements referred to FASB by the Securities and Exchange Commission (“SEC”). The targeted amendments incorporate 14 of the 27 disclosures referred by the SEC into codification. Each amendment in ASU 2023-06 is effective on either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. The Company does not believe the amendments in ASU 2023-06 will have a material impact in any of the Company’s current disclosures.

3. REVENUES

The Company enters into contracts with its clients that contain various types of pricing provisions, including fixed price, time-and-materials, and unit-based provisions. The Company recognizes revenues in accordance with ASU 2014-09, Revenue from Contracts with Customer, codified as ASC Topic 606 and the related amendments (collectively “ASC 606”). As such, the Company identifies a contract with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to each performance obligation in the contract and recognizes revenues when (or as) the Company satisfies a performance obligation.

The following table reflects the Company’s two reportable segments and the types of contracts that each most commonly enters into for revenue generating activities.

​

Segment | Contract Type | Revenue Recognition Method
​ | Time-and-materials | Time-and-materials
Energy | Unit-based | Unit-based
​ | Software license | Unit-based
​ | Fixed price | Percentage-of-completion
​ | Time-and-materials | Time-and-materials
Engineering and Consulting | Unit-based | Unit-based
​ | Fixed price | Percentage-of-completion

​

Revenue on the vast majority of the Company’s contracts is recognized over time because of the continuous transfer of control to the customer. Revenue on fixed price contracts is recognized on the percentage-of-completion method based generally on the ratio of direct costs incurred-to-date to estimated total direct costs at completion. The Company uses the percentage-of-completion method to better match the level of work performed at a certain point in time in relation to the effort that will be required to complete a project. In addition, the percentage-of-completion method is a common method of revenue recognition in the Company’s industry.

Many of the Company’s fixed price contracts involve a high degree of subcontracted fixed price effort and, usually, are relatively short in duration, thereby lowering the risks of not properly estimating the percent complete. Revenue on time-and-materials and unit-based contracts is recognized as the work is performed in accordance with the specific rates and terms of the contract. The Company recognizes revenues for time-and-materials contracts based upon the actual hours incurred during a reporting period at contractually agreed upon rates per hour and also includes in revenue all reimbursable costs incurred during a reporting period. Certain of the Company’s time-and-materials contracts are subject to maximum contract values and, accordingly, when revenue is expected to exceed the maximum contract value, these contracts are generally recognized under the percentage-of-completion method, consistent with fixed price contracts. For unit-based contracts, the Company recognizes the contract price of units of a basic production product as revenue when the production product is delivered during a period. Revenue for amounts that have been billed but not earned is deferred, and such deferred revenue is referred to as contract liabilities in the accompanying condensed consolidated balance sheets. The Company also derives revenue from software licenses and professional services and maintenance fees. In accordance with ASC 606, the Company performs an assessment of each contract to identify the performance obligations, determine the overall transaction price for the contract, allocate the transaction price to the performance obligations, and recognize the revenue when the performance obligations are satisfied. The Company utilizes the residual approach by which it estimates the standalone selling price by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract. The software license revenue is typically recognized at a point in time when control is transferred to the client, which is defined as the point in time when the client can use and benefit from the license. The software license is delivered before related services are provided and is functional without services, updates, or technical support. Related professional services include training and support services in which the standalone selling price is determined based on an input measure of hours incurred to total estimated hours and is recognized over time, which usually is the life of the contract.

To determine the proper revenue recognition method for contracts, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined contract should be accounted for as one performance obligation. With respect to the Company’s contracts, it is rare that multiple contracts should be combined into a single performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because the Company provides a significant service of integrating a complex set of tasks and components into a single project or capability.

The Company may enter into contracts that include separate phases or elements. If each phase or element is negotiated separately based on the technical resources required and/or the supply and demand for the services being provided, the Company evaluates if the contracts should be segmented. If certain criteria are met, the contracts would be segmented which could result in revenues being assigned to the different elements or phases with different rates of profitability based on the relative value of each element or phase to the estimated total contract revenue. Segmented contracts may comprise up to approximately 2.0% to 3.0% of the Company’s consolidated contract revenue.

Contracts that cover multiple phases or elements of the project or service lifecycle (development, construction and maintenance and support) may be considered to have multiple performance obligations even when they are part of a single contract. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. For the periods presented, the value of the separate performance obligations under contracts with multiple performance obligations (generally measurement and verification tasks under certain energy performance contracts) were not material. In cases where the Company does not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts the Company’s expected costs of satisfying a performance obligation and then adds an appropriate margin for the distinct good or service.

The Company provides quality of workmanship warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications and industry standards. The Company does not consider these types of warranties to be separate performance obligations.

In some cases, the Company has a master service or blanket agreement with a customer under which each task order releases the Company to perform specific portions of the overall scope in the service contract. Each task order is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations, and payment terms.

Under ASC 606, variable consideration should be considered when determining the transaction price and estimates should be made for the variable consideration component of the transaction price, as well as assessing whether an estimate of variable consideration is constrained. For certain of the Company’s contracts, variable consideration can arise from modifications to the scope of services resulting from unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on assessments of legal enforceability, the Company’s performance, and all information (historical, current and forecasted) that is reasonably available to the Company.

Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company reviews and updates the Company’s contract-related estimates regularly through a company-wide disciplined project review process in which management reviews the progress and execution of the Company’s performance obligations and the estimate at completion (“EAC”). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables.

The Company recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the full amount of estimated loss in the period it is identified.

Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new rights or obligations or changes the existing enforceable rights or obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification that is not distinct from the existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

For contract modifications that result in the promise to deliver goods or services that are distinct from the existing contract and the increase in price of the contract is for the same amount as the standalone selling price of the additional goods or services included in the modification, the Company accounts for such contract modifications as a separate contract.

The Company includes claims to vendors, subcontractors and others as a receivable and a reduction in recognized costs when enforceability of the claim is established by the contract and the amounts are reasonably estimable and probable of being recovered. The amounts are recorded up to the extent of the lesser of the amounts management expects to recover or to costs incurred.

Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the percentage-of-completion method of revenue recognition.

Direct costs of contract revenue consist primarily of that portion of technical and nontechnical salaries and wages that has been incurred in connection with revenue producing projects. Direct costs of contract revenue also include production expenses, subcontractor services and other expenses that are incurred in connection with revenue producing projects.

Direct costs of contract revenue exclude that portion of technical and nontechnical salaries and wages related to marketing efforts, vacations, holidays and other time not spent directly generating revenue under existing contracts. Such costs are included in general and administrative expenses. Additionally, payroll taxes, bonuses and employee benefit costs for all Company personnel are included in general and administrative expenses in the accompanying condensed consolidated statements of comprehensive income since no allocation of these costs is made to direct costs of contract revenue. No allocation of facilities costs is made to direct costs of contract revenue. Other companies may classify as direct costs of contract revenue some of the costs that the Company classifies as general and administrative costs. The Company expenses direct costs of contract revenue when incurred.

Included in revenue and costs are all reimbursable costs for which the Company has the risk or on which the fee was based at the time of bid or negotiation. No revenue or cost is recorded for costs in which the Company acts solely in the capacity of an agent and has no risks associated with such costs.

Accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts based upon a review of all outstanding amounts on a quarterly basis. Management determines allowances for doubtful accounts through specific identification of amounts considered to be uncollectible and potential write-offs, plus a non-specific allowance for other amounts for which some potential loss has been determined to be probable based on current and past experience. The Company’s historical credit losses have been minimal with governmental entities and large public utilities, but disputes may arise related to these receivable amounts. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received.

Retainage, included in contract assets, represents amounts withheld from billings to the Company’s clients pursuant to provisions in the contracts and may not be paid to the Company until specific tasks are completed or the project is completed and, in some instances, for even longer periods. As of June 28, 2024 and December 29, 2023, contract assets included retainage of approximately $17.6 million and $14.3 million, respectively.

​

Under certain utility contracts, the Company periodically receives cash deposits to be held in trust for the payment of energy incentive rebates to be sent directly to the utility’s end-customer on behalf of the utility. The Company acts solely as the utility’s agent to distribute these funds to the end-customer and, accordingly, the Company classifies these contractually restricted funds as restricted cash. Because these funds are held in trust for pass through to the utility’s customers and have no impact on the Company’s working capital or operating cash flows, these cash receipts are presented in the condensed consolidated statement of cash flows as financing cash inflows, “Receipt of restricted cash”, with the subsequent payments classified as financing cash outflows, “Payment of restricted cash.”

The Company tests its goodwill at least annually for possible impairment. The Company completes its annual testing of goodwill as of the last day of the first month of its fourth fiscal quarter each year to determine whether there is a potential impairment. In addition to the Company’s annual test, it regularly evaluates whether events and circumstances have occurred that may indicate a potential impairment of goodwill. The Company evaluated the current economic environment and noted that it does not believe it is more likely than not that goodwill was impaired as of June 28, 2024.

5. DERIVATIVE FINANCIAL INSTRUMENTS

The Company uses certain interest rate derivative contracts to hedge interest rate exposures on its variable rate debt. The Company’s hedging program is not designated for trading or speculative purposes.

The Company recognizes derivative instruments as either assets or liabilities on the accompanying condensed consolidated balance sheets at fair value. The Company records changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as cash flow hedges in its consolidated balance sheets as accumulated other comprehensive income (loss), and in its consolidated statements of comprehensive income (loss) as unrealized gain or loss on derivative contracts. All related cash flows are reported in the operating activities section of the consolidated statements of cash flows.

On November 30, 2023, the Company entered into an interest rate swap agreement that the Company designated as cash flow hedge to fix the variable interest rate on a portion of the Company’s term loan (see Note 6, “Debt Obligations” for information regarding our indebtedness). The interest rate swap agreement has a total notional amount of $50.0 million, has a fixed annual interest rate of 4.77%, and expires on September 29, 2026. As of June 28, 2024, the effective portion of the Company’s interest rate swap agreement designated as a cash flow hedge before tax effects was $0.7 million, of which no amounts were reclassified from accumulated other comprehensive income (loss) to interest expense in the six months ended June 28, 2024. The Company expects to reclassify $0.1 million from accumulated other comprehensive income (loss) to interest expense within the next twelve months.

The fair values of the Company’s outstanding derivatives designated as hedging instruments were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ |  | Fair Value of Derivative
​ |  | ​ |  | Instruments as of
​ | ​ | Balance Sheet Location | ​ | June 28, 2024 | ​ | December 29, 2023

Interest rate swap agreement | ​ | Current assets | ​ | $ | 138 | ​ | $ | 46
Interest rate swap agreement | ​ | Other noncurrent liabilities | ​ | ​ | (302) | ​ | ​ | (887)

​

The impact of the effective portions of derivative instruments in cash flow hedging relationships and fair value relationships on other comprehensive income (loss) were $0.1 million and $0.5 million for the three and six months ended June 28, 2024.

​

The credit agreement governing the Company’s Term Loan and Revolving Credit Facility require the Company to comply with certain financial obligations, including a maximum Net Leverage Ratio and a minimum Fixed Charge Coverage Ratio (as defined in the credit agreement governing the Term Loan and Revolving Credit Facility). The credit agreement also contains customary restrictive covenants. As of June 28, 2024, the Company was in compliance with all these covenants.

In addition, as of June 28, 2024, the Company’s composite interest rate, exclusive of the effects of upfront fees, undrawn fees and issuance cost amortization, was 7.7%.

7. LEASES

The Company leases certain office facilities under long-term, non-cancellable operating leases that expire at various dates through 2029. In addition, the Company is obligated under finance leases for certain furniture and office equipment that expire at various dates through 2028.

From time to time, the Company enters into non-cancelable leases for some of its facility and equipment needs. These leases allow the Company to conserve cash by paying a monthly lease rental fee for the use of facilities and equipment rather than purchasing them. The Company’s leases typically have remaining terms ranging from one to eight years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases within one year. Currently, all of the Company’s leases contain fixed payment terms. The Company may decide to cancel or terminate a lease before the end of its term, in which case the Company is typically liable to the lessor for the remaining lease payments under the term of the lease. Additionally, all of the Company’s month-to-month leases are cancelable by the Company or the lessor, at any time, and are not included in the Company’s right-of-use asset or lease liability. As of June 28, 2024, the Company had no leases with residual value guarantees. Typically, the Company has purchase options on the equipment underlying its long-term leases. The Company may exercise some of these purchase options when the need for equipment is on-going and the purchase option price is attractive. Nonperformance-related default covenants, cross-default provisions, subjective default provisions and material adverse change clauses contained in material lease agreements, if any, are also evaluated to determine whether those clauses affect lease classification in accordance with ASC Topic 842-10-25. Leases are accounted for as operating or financing leases, depending on the terms of the lease.

Financing Leases

The Company leases certain equipment under financing leases. The economic substance of the leases is a financing transaction for acquisition of equipment and leasehold improvements. Accordingly, the right-of-use assets for these leases are included in the balance sheets in equipment and leasehold improvements, net of accumulated depreciation, with a corresponding amount recorded in current portion of financing lease obligations or noncurrent portion of financing lease obligations, as appropriate. The financing lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense. The interest associated with financing lease obligations is included in interest expense.

Right-of-use assets

Operating leases are included in right-of-use assets, and current portion of lease liability and noncurrent portion of lease liability, as appropriate. Right-of-use assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate to calculate present value, the Company determines this rate by estimating the Company’s incremental borrowing rate at the lease commencement date. The right-of-use asset also includes any lease payments made and initial direct costs incurred at lease commencement and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

8. COMMITMENTS AND VARIABLE INTEREST ENTITIES

Employee Benefit Plans

The Company has a qualified profit sharing plan pursuant to Code Section 401(a) and qualified cash or deferred arrangement pursuant to Code Section 401(k) covering all employees. Employees may elect to contribute up to 50% of their compensation limited to the amount allowed by tax laws. Company contributions are made solely at the discretion of the Company’s board of directors.

The Company’s defined contribution plan (the “Plan”) covers employees who have completed three months of service and who have attained 21 years of age. The Company elects to make matching contributions equal to 50% of the participants’ contributions to the Plan, up to 6% of the individual participant’s compensation, and subject to a maximum of $3,000 per employee. Under the Plan, the Company may make discretionary contributions to employee accounts.

During the six months ended June 28, 2024 and June 30, 2023, the Company made matching contributions of $1.7 million and $1.6 million, respectively.

Variable Interest Entities

On March 4, 2016, the Company and the Company’s wholly-owned subsidiary, WES, acquired substantially all of the assets of Genesys and assumed certain specified liabilities of Genesys (collectively, the “Purchase”) pursuant to an Asset Purchase and Merger Agreement, dated as of February 26, 2016 (the “Agreement”), by and among Willdan Group, Inc., WES, WESGEN (as defined below), Genesys and Ronald W. Mineo (“Mineo”) and Robert J. Braun (“Braun” and, together with Mineo, the “Genesys Shareholders”). On March 5, 2016, pursuant to the terms of the Agreement, WESGEN, Inc., a non-affiliated corporation (“WESGEN”), merged (the “Merger” and, together with the Purchase, the “Acquisition”) with Genesys, with Genesys remaining as the surviving corporation. Genesys was acquired to strengthen the Company’s power engineering capability in the northeastern U.S., and also to increase client exposure and experience with universities.

Genesys continues to be a professional corporation organized under the laws of the State of New York, wholly-owned by one or more licensed engineers. Pursuant to New York law, the Company does not own capital stock of Genesys. The Company has entered into an agreement with the Shareholder of Genesys pursuant to which the Shareholder will be prohibited from selling, transferring or encumbering the Shareholder’s ownership interest in Genesys without the Company’s consent. Notwithstanding the Company’s rights regarding the transfer of Genesys’s stock, the Company does not have control over the professional decision making of Genesys’s engineering services. The Company has entered into an administrative services agreement with Genesys pursuant to which WES will provide Genesys with ongoing administrative, operational and other non-professional support services. Genesys pays WES a service fee, which consists of all of the costs incurred by WES to provide the administrative services to Genesys plus ten percent of such costs, as well as any other costs that relate to professional service supplies and personnel costs. As a result of the administrative services agreement, the Company absorbs the expected losses of Genesys through its deferral of Genesys’s service fees owed to WES.

​

The Company manages Genesys and has the power to direct the activities that most significantly impact Genesys’s performance, in addition to being obligated to absorb expected losses from Genesys. Accordingly, the Company is the primary beneficiary of Genesys and consolidates Genesys as a VIE. In addition, the Company concluded there is no noncontrolling interest related to the consolidation of Genesys because the Company determined that (i) the shareholder of Genesys does not have more than a nominal amount of equity investment at risk, (ii) WES absorbs the expected losses of Genesys through its deferral of Genesys’s service fees owed to WES and the Company has, since entering into the administrative services agreement, had to continuously defer service fees for Genesys, and (iii) the Company believes Genesys will continue to have a shortfall on payment of its service fees for the foreseeable future, leaving no expected residual returns for the shareholder. As of June 28, 2024, the Company had one VIE — Genesys.

9. SEGMENT AND GEOGRAPHICAL INFORMATION

Segment Information

The Company’s two segments are Energy, and Engineering and Consulting, and the Company’s chief operating decision maker, which continues to be its chief executive officer, receives and reviews financial information in this format.

There were no intersegment sales during the three and six months ended June 28, 2024 and June 30, 2023. The Company’s chief operating decision maker evaluates the performance of each segment based upon income or loss from operations before income taxes. Certain segment asset information including expenditures for long-lived assets has not been presented as it is not reported to or reviewed by the chief operating decision maker. In addition, enterprise-wide service line contract revenue is not included as it is impracticable to report this information for each group of similar services.

10. INCOME TAXES

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial reporting basis and tax basis of the Company’s assets and liabilities, subject to a judgmental assessment of the recoverability of deferred tax assets. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets may not be realized. Significant judgment is applied when assessing the need for valuation allowances and includes the evaluation of historical income (loss) adjusted for the effects of non-recurring items and the impact of recent business combinations. Areas of estimation include the Company’s consideration of future taxable income which is driven by verifiable signed contracts and ongoing prudent and feasible tax planning strategies. Should a change in circumstances lead to a change in judgment about the utilization of deferred tax assets in future years, the Company would adjust the related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income.

At the end of fiscal year 2023, the Company’s total valuation allowance was $1.2 million, remaining unchanged from the end of fiscal year 2022. As of June 28, 2024, the Company assessed all available positive and negative evidence available to determine whether, based on the weight of that evidence, there was a change in judgment related to the utilization of deferred tax assets in future years. The Company concluded that as of June 28, 2024, the valuation allowance for the Company’s deferred tax assets was appropriate in accordance with ASC 740. Consequently, there was no change to the valuation allowance during the three and six months ended June 28, 2024.

For acquired business entities, if the Company identifies changes to acquired deferred tax asset valuation allowances or liabilities related to uncertain tax positions during the measurement period and they relate to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement period adjustment, and the Company records the offset to goodwill. The Company records all other changes to deferred tax asset valuation allowances and liabilities related to uncertain tax positions in current period income tax expense.

The Company recognizes the tax benefit from uncertain tax positions if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. During the three and six months ended June 28, 2024, and the three and six months ended June 30, 2023, the Company did not record a liability for uncertain tax positions.

Based on the Company’s estimates and determination of an effective tax rate for the year, the Company recorded an income tax expense of $0.7 million and $1.7 million for the three and six months ended June 28, 2024, respectively, compared to an income tax expense of $0.2 million and $1.0 million for the three and six months ended June 30, 2023, respectively. During the three and six months ended June 28, 2024, the difference between the effective tax rate and the federal statutory rate was primarily attributable to state taxes, non-deductible stock compensation, nondeductible executive compensation, research and development tax credits, and the commercial building energy efficiency deduction. During the three and six months ended June 30, 2023, the difference between the effective tax rate and the federal statutory rate was primarily attributable to state taxes, non-deductible stock compensation, nondeductible executive compensation, research and development tax credits, and the commercial building energy efficiency deduction.

11. EARNINGS PER SHARE (“EPS”)

Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding and dilutive potential common shares for the period. Potential common shares include the weighted-average dilutive effects of outstanding stock options and restricted stock awards using the treasury stock method.

The following table sets forth the number of weighted-average common shares outstanding used to compute basic and diluted EPS:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three months ended | ​ | Six months ended
​ | ​ | June 28, | ​ | June 30, | ​ | June 28, | ​ | June 30,
​ |  | 2024 |  | 2023 |  | 2024 |  | 2023
​ | ​ | (in thousands, except per share amounts)
Net income (loss) | ​ | $ | 4,594 | ​ | $ | 397 | ​ | $ | 7,536 | ​ | $ | 1,329
Weighted-average common shares outstanding | ​ |  | 13,725 | ​ |  | 13,344 | ​ |  | 13,665 | ​ |  | 13,305
Effect of dilutive stock options and restricted stock awards | ​ |  | 349 | ​ |  | 143 | ​ |  | 336 | ​ |  | 176
Weighted-average common shares outstanding-diluted | ​ |  | 14,074 | ​ |  | 13,487 | ​ |  | 14,001 | ​ |  | 13,481
Earnings (Loss) per share: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Basic | ​ | $ | 0.33 | ​ | $ | 0.03 | ​ | $ | 0.55 | ​ | $ | 0.10
Diluted | ​ | $ | 0.33 | ​ | $ | 0.03 | ​ | $ | 0.54 | ​ | $ | 0.10

​

For the three and six months ended June 28, 2024, the Company excluded 273,000 and 409,000 common shares subject to outstanding equity awards, respectively, from the calculation of diluted shares because their impact would have been anti-dilutive. For the three and six months ended June 30, 2023, the Company excluded 451,000 and 433,000 common shares subject to outstanding equity awards, respectively, from the calculation of diluted shares because their impact would have been anti-dilutive.

12. CONTINGENCIES

Claims and Lawsuits

The Company is subject to claims and lawsuits from time to time, including those alleging professional errors or omissions that arise in the ordinary course of business against firms that operate in the engineering and consulting professions. The Company carries professional liability insurance, subject to certain deductibles and policy limits, for such claims as they arise and may from time to time establish reserves for litigation that is considered probable of a loss.

In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, and discloses the amount accrued and an estimate of any reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for the Company’s financial statements not to be misleading. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote.

Because litigation outcomes are inherently unpredictable, the Company’s evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. If the assessments indicate that loss contingencies that could be material to any one of the Company’s financial statements are not probable, but are reasonably possible, or are probable, but cannot be estimated, then the Company will disclose the nature of the loss contingencies, together with an estimate of the possible loss or a statement that such loss is not reasonably estimable. While the consequences of certain unresolved proceedings are not presently determinable, and a reasonable estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of the Company’s management, after consulting with legal counsel, and taking into account insurance coverage, the ultimate liability related to current outstanding claims and lawsuits is not expected to have a material adverse effect on the Company’s financial statements.

Direct costs of contract revenue. Direct costs of consolidated contract revenue increased $13.7 million, or 17.5%, for the three months ended June 28, 2024, compared to the three months ended June 30, 2023, primarily as a result of the increase, and change of mix, in contract revenues as described above. As a percentage of contract revenue, direct salaries and wages decreased to 16.8% in the three months ended June 28, 2024 from 17.9% in the three months ended June 30, 2023, while subcontractor services and other direct costs increased to 48.6% in the three months ended June 28, 2024 from 48.0% in the three months ended June 30, 2023.

Direct costs of contract revenue in our Energy segment increased $13.0 million, or 19.0%, for the three months ended June 28, 2024, compared to the three months ended June 30, 2023. Direct costs of contract revenue for the Engineering and Consulting segment increased $0.7 million, or 7.5%, in the three months ended June 28, 2024, compared to the three months ended June 30, 2023.

Subcontractor services and other direct costs increased by $11.4 million, or 20.0%, in the three months ended June 28, 2024, compared to the three months ended June 30, 2023, primarily due to the increase in construction management revenues, which utilize a higher percentage of material cost and installation subcontracting. Salaries and wages increased by $2.3 million, or 11.0%, in the three months ended June 28, 2024, compared to the three months ended June 30, 2023, primarily as a result of the increases in contract revenue as described above.

Gross Profit. Gross profit increased 20.1% to $48.8 million, or 34.6% gross margin, for the three months ended June 28, 2024, compared to gross profit of $40.6 million, or 34.1% gross margin, for the three months ended June 30, 2023. The increase in our gross margin was primarily driven by changes in the mix of revenues as described above.

General and administrative expenses. General and administrative (“G&A”) expenses increased $4.2 million, or 11.0%, in the three months ended June 28, 2024, compared to the three months ended June 30, 2023. G&A expenses consisted of an increase of $2.2 million in the Energy segment combined with an increase of $1.6 million in the Engineering and Consulting segment, and an increase of $0.4 million in unallocated corporate expenses.

Within G&A expenses, the increase of $3.6 million in salaries and wages, payroll taxes and employee benefits, combined with the increase of $0.7 million in stock-based compensation, and the increase of $0.6 million in other general and administrative expenses was partially offset by a decrease of $0.5 million in depreciation and amortization. The increase in salaries and wages, payroll taxes and employee benefits was primarily due to an increase in incentive compensation, consistent with the improvement in operating profit, and higher fringe benefit costs. The increase in stock-based compensation expenses was primarily related to new stock grants to current employees and executives. The increase in other general and administrative expenses was primarily due to increased professional service fees and computer-related expenses. The decrease in depreciation and amortization was primarily related to lower amortization of intangible assets from prior acquisitions.

Income (loss) from operations. Operating income increased to $6.4 million for the three months ended June 28, 2024, compared to an operating income of $2.5 million for the three months ended June 30, 2023, as a result of the factors noted above.

Total other expense, net. Total other expense, net, decreased $0.7 million, or 38.2%, for the three months ended June 28, 2024, compared to the three months ended June 30, 2023, primarily due to increased interest income related to our higher cash balances, combined with lower interest expense resulting from the reduced interest rate spread derived from lower debt leverage levels under our credit facilities.

Income tax expense (benefit). We recorded an income tax expense of $0.7 million for the three months ended June 28, 2024, an effective tax rate of 13.5% on income before income tax expense, compared to an income tax expense of $0.2 million for the three months ended June 30, 2023, an effective tax rate of 38.0% on income before tax expense. The reduction in the effective tax rate resulted from increases in discrete items related to stock compensation deductions.

G&A expenses consisted of an increase of $5.4 million in the Energy segment combined with an increase of $3.3 million in the Engineering and Consulting segment, and an increase of $0.3 million in unallocated corporate expenses.

Within G&A expenses, the increase of $7.8 million in salaries and wages, payroll taxes and employee benefits, combined with the increase of $1.9 million in other general and administrative expenses, and the increase of $0.5 million in stock-based compensation was partially offset by a decrease of $1.1 million in depreciation and amortization. The increase in salaries and wages, payroll taxes and employee benefits was primarily due to an increase in incentive compensation, consistent with the improvement in operating profit, and higher fringe benefit costs. The increase in other general and administrative expenses was primarily due to increased professional service fees and computer-related expenses. The increase in stock-based compensation expenses was primarily related to new stock grants to current

employees and executives. The decrease in depreciation and amortization was primarily related to lower amortization of intangible assets from prior acquisitions.

Income (loss) from operations. Operating income increased 82.0% to $11.8 million for the six months ended June 28, 2024, compared to an operating income of $6.5 million for the six months ended June 30, 2023, as a result of the factors noted above.

Total other expense, net. Total other expense, net, decreased $1.6 million, or 38.3%, for the six months ended June 28, 2024, compared to the six months ended June 30, 2023, primarily due to increased interest income related to our higher cash balances, combined with lower interest expense resulting from the reduced interest rate spread derived from lower debt leverage levels under our credit facilities.

Income tax expense (benefit). We recorded an income tax expense of $1.7 million for the six months ended June 28, 2024, an effective tax rate of 18.5% on income before income tax expense, compared to an income tax expense of $1.0 million for the six months ended June 30, 2023, an effective tax rate of 42.9% on income before tax expense. The reduction in the effective tax rate resulted from increases in discrete items related to stock compensation deductions.

Net income (loss). Our net income was $7.5 million for the six months ended June 28, 2024, as compared to a net income of $1.3 million for the six months ended June 30, 2023. The increase in net income was primarily attributable to the increase in income from operations combined with the decrease in total other expense, net and the lower effective tax rate.

Sources of Cash

Our primary sources of liquidity for the next 12 months and beyond are cash generated from operations, cash and cash equivalents, and available borrowings under our revolving credit facility under the Credit Agreement (the “Revolving Credit Facility”). We believe that our cash and cash equivalents, cash generated by operating activities, and available borrowings under our Revolving Credit Facility will be sufficient to finance our operating activities for at least the next 12 months.

As of June 28, 2024, we had a fully drawn $100 million term loan with $94.4 million outstanding (the “Term Loan”), and a $50.0 million Revolving Credit Facility with no borrowed amounts and $1.6 million in letters of credit issued, each scheduled to mature on September 29, 2026. In addition, as of June 28, 2024, we had $44.3 million of unrestricted cash and cash equivalents.

Table of Contents

As of June 28, 2024, unhedged borrowings under our Credit Facilities, exclusive of the effects of upfront fees, undrawn fees and issuance cost amortization, bore interest at an annual rate of 7.7%. See Part I, Item 1, Note 6, “Debt Obligations”, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, and Part II, Item 8, Note 6, “Debt Obligations”, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023, for information regarding our indebtedness, including information about borrowings and repayments, principal repayment terms, interest rates, covenants, and other key terms of our outstanding indebtedness.

Cash Flows from Operating Activities

Cash flows provided by operating activities were $27.8 million for the six months ended June 28, 2024, as compared to cash flows provided by operating activities of $18.9 million for the six months ended June 30, 2023. Cash flows from operating activities primarily consists of net income, adjusted for non-cash charges, such as depreciation and amortization and stock-based compensation, plus or minus changes in current operating assets and liabilities. Cash flows provided by operating activities for the six months ended June 28, 2024, resulted primarily from the increase in earnings and lower working capital requirements. Cash flows provided by operating activities for the six months ended June 30, 2023, resulted primarily from the increase in earnings, combined with lower working capital requirements.

Cash Flows from Investing Activities

Cash flows used in investing activities were $4.1 million for the six months ended June 28, 2024, as compared to cash flows used in investing activities of $5.7 million for the six months ended June 30, 2023. Cash flows used in investing activities for the six months ended June 28, 2024 and for the six months ended June 30, 2023, were primarily due to cash paid for the development of software and the purchase of computers and equipment.

Cash Flows from Financing Activities

Cash flows used in financing activities were $2.9 million for the six months ended June 28, 2024, as compared to cash flows used in financing activities of $19.0 million for the six months ended June 30, 2023. Cash flows used in financing activities for the six months ended June 28, 2024 were primarily attributable to the repayments of $3.8 million under our Term Loan, $0.8 million cash used to pay withholding taxes on stock grants, and $0.7 million principal payments on finance leases, partially offset by $1.4 million of proceeds from sales of common stock under employee stock purchase plan and $1.1 million in proceeds from stock option exercise. Cash flows used in financing activities for the six months ended June 30, 2023 were primarily attributable to the disbursement of the $10.7 million in restricted cash for utility rebate incentives, repayments of $9.0 million under our term loan facility and revolving line of credit, and payments of $4.0 million for contingent consideration related to prior acquisitions, partially offset by borrowings of $5.0 million under our revolving line of credit.

Under certain utility contracts, we periodically receive cash deposits to be held in trust for the payment of energy incentive rebates to be sent directly to the utility’s end-customer on behalf of the utility. We act solely as the utility’s agent to distribute these funds to the end-customer and, accordingly, we classify these contractually restricted funds as restricted cash. Because these funds are held in trust for pass through to the utility’s customers and have no impact on our working capital or operating cash flows, these cash receipts are presented in the consolidated statement of cash flows as financing cash inflows, “Receipt of restricted cash”, with the subsequent payments classified as financing cash outflows, “Payment of restricted cash.”

Off-Balance Sheet Arrangements

We do not have any off-balance sheet financing arrangements or liabilities. In addition, our policy is not to enter into futures or forward contracts. Finally, we do not have any majority-owned subsidiaries or any interests in, or relationships with, any special-purpose entities that are not included in the consolidated financial statements. We have, however, an administrative services agreement with Genesys in which we provide Genesys with ongoing administrative, operational and other non-professional support services. We manage Genesys and have the power to direct the activities

38

Table of Contents

that most significantly impact Genesys’ performance, in addition to being obligated to absorb expected losses from Genesys. Accordingly, we are the primary beneficiary of Genesys and consolidate Genesys as a variable interest entity.

Short and Long-term Uses of Cash

General

Our principal uses of cash are to fund operating expenses, support working capital requirements, finance capital expenditures, and pay down outstanding debt. From time to time, we also use cash to help fund business acquisitions. Our cash and cash equivalents are impacted by the timing of when we invoice and are paid by our customers for services rendered and when we pay expenses as reflected in the change in our outstanding accounts payable and accrued expenses.

Contractual Obligations

The following table sets forth our known contractual obligations as of June 28, 2024:

Outstanding Indebtedness

See Part I, Item 1, Note 6, “Debt Obligations”, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, and Part II, Item 8, Note 6, “Debt Obligations”, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023, for information regarding our indebtedness, including information about new borrowings and repayments, principal repayment terms, interest rates, covenants, and other key terms of our outstanding indebtedness.

Interest Rate Swap

From time to time, we enter into interest rate swap agreements to moderate our exposure to fluctuations in interest rates underlying our variable rate debt. For more information, see Part I, Item 3, “Quantitative and Qualitative Disclosures About Market Risk”, and Note 5, “Derivative Financial Instruments”, to the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Impact of Inflation

Due to the average duration of our projects and our ability to negotiate prices as contracts end and new contracts begin, historically, our operations have not been materially impacted by inflation.

​

While immaterial to our results of operations and financial condition, we have experienced higher cost of materials and delays in our supply chain for equipment. The prices of finished products from manufacturers are subject to fluctuation and increases. It is difficult to accurately measure the impact of inflation, tariffs, price escalation, raw material costs, and other factors that impact the cost of finished goods due to the imprecise nature of the estimates required.

​

We are often able to mitigate the impact of future price increases by entering into fixed price purchase orders for materials and equipment, and subcontracts on our projects, as well as, when appropriate, including cost escalation factors into our proposals. Despite our best mitigation efforts, significant price increases in equipment and disruptions to our supply chain could materially impact our results of operations and financial condition. In addition, inflationary pressures, including expectations of future inflation, may impact the customers of our utility clients, which may lead to delayed or deferred decisions regarding expenditures to improve energy efficiency, and therefore potentially impact our future revenues.

Components of Revenue and Expense

Contract Revenue

We generally provide our services under contracts, purchase orders or retainer letters. The agreements we enter into with our clients typically incorporate one of three principal types of pricing provisions: time-and-materials, unit-based, and fixed price. Revenue on our time-and-materials and unit-based contracts are recognized as the work is performed in accordance with specific terms of the contract. As of June 28, 2024, 19% of our contracts are time-and-materials contracts, 39% are unit-based contracts, and 42% are fixed price contracts, compared to 21% are time-and-materials contracts, 42% are unit-based contracts, and 37% are fixed price contracts, as of June 30, 2023.

Some of these contracts include maximum contract prices, but contract maximums are often adjusted to reflect the level of effort to achieve client objectives and thus the majority of these contracts are not expected to exceed the maximum. Contract revenue on our fixed price contracts is determined on the percentage of completion method based generally on the ratio of direct costs incurred to date to estimated total direct costs at completion. Many of our fixed price contracts involve a high degree of subcontracted fixed price effort and are relatively short in duration, thereby lowering the risks of not properly estimating the percent complete.

Adjustments to contract cost estimates are made in the periods in which the facts requiring such revisions become known. When the revised estimate indicates a loss, such loss is recognized in the current period in its entirety. Claims and change orders that have not been finalized are evaluated to determine whether or not a change has occurred in the enforceable rights and obligations of the original contract. If these non-finalized changes qualify as a contract modification, a determination is made whether to account for the change in contract value as a modification to the existing contract, or a separate contract and revenue under the claims or change orders is recognized accordingly. Costs related to un-priced change orders are expensed when incurred, and recognition of the related revenue is based on the assessment above of whether or not a contract modification has occurred. Estimated profit for un-priced change orders is recognized only if collection is probable.

Our contracts come up for renewal periodically and at the time of renewal may be subject to renegotiation, which could impact the profitability on that contract. In addition, during the term of a contract, public agencies may request additional or revised services which may impact the economics of the transaction. Most of our contracts permit our clients, with prior notice, to terminate the contracts at any time without cause. While we have a large volume of contracts, the renewal, termination or modification of a contract, in particular contracts with Consolidated Edison, the Dormitory Authority-State of New York, the New York City Housing Authority, and utility programs associated with

40

Table of Contents

Los Angeles Department of Water and Power and Duke Energy Corp., may have a material effect on our consolidated operations.

Some of our contracts include certain performance guarantees, such as a guaranteed energy saving quantity. Such guarantees are generally measured upon completion of a project. In the event that the measured performance level is less than the guaranteed level, any resulting financial penalty, including any additional work that may be required to fulfill the guarantee, is estimated and charged to direct expenses in the current period. We have not experienced any significant costs under such guarantees.

Direct Costs of Contract Revenue

Direct costs of contract revenue consist primarily of that portion of salaries and wages that have been incurred in connection with revenue producing projects. Direct costs of contract revenue also include material costs, subcontractor services, equipment and other expenses that are incurred in connection with revenue producing projects. Direct costs of contract revenue exclude that portion of salaries and wages related to marketing efforts, vacations, holidays and other time not spent directly generating revenue under existing contracts. Such costs are included in general and administrative expenses. Additionally, payroll taxes, bonuses and employee benefit costs for all of our personnel are included in general and administrative expenses since no allocation of these costs is made to direct costs of contract revenue.

Other companies may classify as direct costs of contract revenue some of the costs that we classify as general and administrative costs. We expense direct costs of contract revenue when incurred.

General and Administrative Expenses

G&A expenses include the costs of the marketing and support staff, other marketing expenses, management and administrative personnel costs, payroll taxes, bonuses and employee benefits for all of our employees and the portion of salaries and wages not allocated to direct costs of contract revenue for those employees who provide our services. G&A expenses also include facility costs, depreciation and amortization, professional services, legal and accounting fees and administrative operating costs. Within G&A expenses, “Other” includes expenses such as professional services, legal and accounting, computer costs, travel and entertainment, marketing costs and acquisition costs. We expense general and administrative costs when incurred.

Critical Accounting Policies

We have prepared the accompanying unaudited Condensed Consolidated Financial Statements in accordance with generally accepted accounting principles in the U.S. (“GAAP”). To prepare these financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses in the reporting period. Our actual results may differ from these estimates. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate.

There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10-K for our fiscal year ended December 29, 2023. Please refer to Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 29, 2023 for a discussion of our critical accounting policies and estimates.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Market risk is the risk of loss to future earnings, to fair values or to future cash flows that may result from changes in the price of a financial instrument. The value of a financial instrument may change as a result of changes in interest rates, exchange rates, commodity prices, equity prices and other market changes. Market risk is attributed to all market risk sensitive financial instruments, including long-term debt.

As of June 28, 2024, we had cash and cash equivalents of $44.3 million. This amount represents cash on hand in business checking accounts with BMO Bank, N.A. We do not engage in trading activities and do not participate in foreign currency transactions.

We are subject to interest rate risk in connection with our Term Loan and borrowings, if any, under our Revolving Credit Facility, each of which bears interest at variable rates. As of June 28, 2024, $94.4 million was outstanding under our Term Loan, and we had no borrowed amounts outstanding and $1.6 million in letters of credit were issued under our Revolving Credit Facility. Each of our Term Loan and Revolving Credit Facility mature on September 29, 2026 and are governed by our Credit Agreement.

​

Pursuant to the Credit Agreement, (as described in Part II, Item 8, Note 6, “Debt Obligations”, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023), borrowings under the Credit Agreement bear interest at either a Base Rate (as defined in the Credit Agreement) or the adjusted Secured Overnight Financing Rate (“SOFR”), at the Company’s option, and in each case, plus an applicable margin, which applicable margin ranges from 0.75% to 2.00% with respect to Base Rate borrowings and 1.75% to 3.00% with respect to SOFR borrowings, depending on the Company’s Total Net Leverage Ratio (as defined in the Credit Agreement); provided, that SOFR and the Base Rate cannot be less than 0.00%, with the specific pricing reset on each date on which the Administrative Agent receives the required financial statements under the Credit Agreement for the fiscal quarter then ended. The Company must also pay a commitment fee for the unused portion of the Revolving Credit Facility, which ranges from 0.20% to 0.40% per annum depending on the Company’s Total Net Leverage Ratio, and fees on the face amount of any letters of credit outstanding under the Revolving Credit Facility, which range from 1.3125% to 2.25% per annum, in each case, depending on the Company’s Total Net Leverage Ratio, as well as customary fronting fees payable to BMO as letter of credit issuer.

​

The Term Loan will amortize quarterly in an amount equal to (i) 7.5% per annum for the first year ending after the Closing Date and (ii) 10.0% per annum for the second and third years ending after the Closing Date, with a final payment of all then remaining principal and interest due on the maturity date of September 29, 2026. The amounts outstanding under the Credit Facilities may be prepaid in whole or in part at any time without penalty (other than customary breakage costs).

​

On November 30, 2023, we entered into an interest rate swap agreement for $50.0 million notional amount. The interest swap agreement was designated as a cash flow hedge to fix the variable interest rate on a portion of the outstanding principal amount under our Term Loan. The interest rate swap fixed rate is 4.77% and expires on September 29, 2026.

​

Based upon the amount of our outstanding indebtedness as of June 28, 2024, a one percentage point increase in the effective interest rate, inclusive of our interest rate swap agreement, would change our annual interest expense by approximately $0.4 million in fiscal year 2024.

ITEM 4. Controls and Procedures

​

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) and Rule 15-d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as controls and other procedures that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act is accumulated and communicated to our management, including our including our President and Chief Executive Officer, Michael A. Bieber, and our Chief Financial Officer and Executive Vice President, Creighton K. Early, as appropriate to allow timely decisions regarding required disclosure.

​

In connection with the preparation of this Quarterly Report, an evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of June 28, 2024. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective, at a reasonable assurance level, as of June 28, 2024.

​

No change in our internal control over financial reporting occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

We are subject to claims and lawsuits from time to time, including those alleging professional errors or omissions that arise in the ordinary course of business against firms that operate in the engineering and consulting professions. We carry professional liability insurance, subject to certain deductibles and policy limits, for such claims as they arise and may from time to time establish reserves for litigation that is considered probable of a loss.

In accordance with accounting standards regarding loss contingencies, we accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, and we disclose the amount accrued and an estimate of any reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our financial statements not to be misleading. We do not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote.

Because litigation outcomes are inherently unpredictable, our evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. If the assessments indicate that loss contingencies that could be material to any one of our financial statements are not probable, but are reasonably possible, or are probable, but cannot be estimated, then we disclose the nature of the loss contingencies, together with an estimate of the possible loss or a statement that such loss is not reasonably estimable. While the consequences of certain unresolved proceedings are not presently determinable, and a reasonable estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be made, an adverse outcome from such proceedings could have a material adverse effect on our earnings in any given reporting period. However, in the opinion of our management, after consulting with legal counsel, and taking into account insurance coverage, the ultimate liability related to current outstanding claims and lawsuits is not expected to have a material adverse effect on our financial statements.
